Analog and Digital Communication Mini Projects | FM, Telecommunication, Mod...

 

Mini Project Ideas


1. You can do your mini project on analog communication topic such as FM, walkie-talkie, etc.

[1.1] Analog Communication Based Project

[1.2] MATLAB Code for Frequency Modulation (FM)


2. Compare the ASK, FSK, and PSK systems' relative performances.

(Include an introduction, concise descriptions of ASK, FSK, and PSK, MATLAB, and Simulink. You can then compare ASK, FSK, and PSK by creating BER vs. SNR graphs for each of those modulations, as well as by comparing their bandwidth, noise resistivity, complexity, and other characteristics.)

3. M-ary Modulation Based Mini Projects

(You can go for this project if you are interested in doing projects based on frequently used and modern modulation techniques. You can compare the performance analysis of various modulation schemes, like, bit rate, complexity, SNR v/s BER graph. You know frequently used modulation technique is m ary QPSK. But now QAM is also becoming popular due to its less complexity. But there is still some limitations in QAM due to its capacity in the context of noise handling. On the other hand m ary QPSK is better for very large constellation points but this technique is more complex than QAM. So, your primary goal may be investigating up to how many constellation points QAM is better than QPSK. Although, now we don't need to transfer data using QPSK with large constellation points. Obviously, in real world QAM is still used. 

For this mini project you can include a comparison of  bit and baud rate of different modulation techniques. You can start from primary modulation techniques like, ask, fsk to QPSK or QAM)


3. Telecommunication based mini project

(Here, you can discuss mechanism of telecommunication - from end user to telephone exchange office and exchange office to gateway. You can also discuss uplink and downlink connection, operating frequency, modulation used for a particular generation wireless communication. You can include the role of fiber optics in case of telecommunication, etc.)


4. Role of Equalizer in Wireless Communication

Calculation of SNR from FFT bins in MATLAB

๐Ÿ“˜ Overview ๐Ÿงฎ MATLAB Code for Estimation of SNR from FFT bins of a Noisy Signal ๐Ÿงฎ MATLAB Code for Estimation of Signal-to-Noise Ratio from Power Spectral Density Using FFT and Kaiser Window Periodogram from real signal data ๐Ÿ“š Further Reading   Here, you can find the SNR of a received signal from periodogram / FFT bins using the Kaiser operator. The beta (ฮฒ) parameter characterizes the Kaiser window, which controls the trade-off between the main lobe width and the side lobe level in the frequency domain. For that you should know the sampling rate of the signal.  The Kaiser window is a type of window function commonly used in signal processing, particularly for designing finite impulse response (FIR) filters and performing spectral analysis. It is a general-purpose window that allows for control over the trade-off between the main lobe width (frequency resolution) and side lobe levels (suppression of spectral leakage). The Kaiser window is defined...

MIMO Channel Matrix | Rank and Condition Number

MIMO / Massive MIMO MIMO Channel Matrix | Rank and Condition...   The channel matrix in wireless communication is a matrix that describes the impact of the channel on the transmitted signal. The channel matrix can be used to model the effects of the atmospheric or underwater environment on the signal, such as the absorption, reflection or scattering of the signal by surrounding objects. When addressing multi-antenna communication, the term "channel matrix" is used. Let's assume that only one TX and one RX are in communication and there's no surrounding object. Here, in our case, we can apply the proper threshold condition to a received signal and get the original transmitted signal at the RX side. However, in real-world situations, we see signal path blockage, reflections, etc.,  (NLOS paths [↗]) more frequently. The obstruction is typically caused by building walls, etc. Multi-antenna communication was introduced to address this issue. It makes diversity app...

Pulse Position Modulation (PPM)

Pulse Position Modulation (PPM) is a type of signal modulation in which M message bits are encoded by transmitting a single pulse within one of 2แดน possible time positions within a fixed time frame. This process is repeated every T seconds , resulting in a data rate of M/T bits per second . PPM is a form of analog modulation where the position of each pulse is varied according to the amplitude of the sampled modulating signal , while the amplitude and width of the pulses remain constant . This means only the timing (position) of the pulse carries the information. PPM is commonly used in optical and wireless communications , especially where multipath interference is minimal or needs to be reduced. Because the information is carried in timing , it's more robust in some noisy environments compared to other modulation schemes. Although PPM can be used for analog signal modulation , it is also used in digital communications where each pulse position represents a symbol or bit...

What are Precoding and Combining Weights / Matrices in a MIMO Beamforming System

MIMO / Massive MIMO Beamforming Techniques Precoding and Combining Weights...   Figure:  configuration of single-user digital precoder for millimeter  Wave massive MIMO system Precoding and combining are two excellent ways to send and receive signals over a multi-antenna communication process, respectively (i.e., MIMO antenna communication ). The channel matrix is the basis of both the precoding and combining matrices. Precoding matrices are typically used on the transmitter side and combining matrixes on the receiving side. The two matrices allow us to generate multiple simultaneous data streams between the transmitter and receiver. The nature of the data streams is also orthogonal. That helps decrease or cancel (theoretically) interference between any two data streams. The channel matrix is first properly diagonalized. Diagonalization is the process of transforming any matrix into an equivalent diagon...
