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

[Read More] about Channel Estimation and Equalization

(Zero Forcing Equalizer, Least Square (LS) Equalizer, MMSE Equalizer, etc.)

MATLAB Code for Rms Delay Spread

RMS delay spread is crucial when you need to know how much the signal is dispersed in time due to multipath propagation, the spread (variance) around the average. In high-data-rate systems like LTE, 5G, or Wi-Fi, even small time dispersions can cause ISI. RMS delay spread is directly related to the amount of ISI in such systems. RMS Delay Spread [↗] Delay Spread Calculator Enter delays (ns) separated by commas: Enter powers (dB) separated by commas: Calculate   The above calculator Converts Power to Linear Scale: It correctly converts the power values from decibels (dB) to a linear scale. Calculates Mean Delay: It accurately computes the mean excess delay, which is the first moment of the power delay profile. Calculates RMS Delay Spread: It correctly calculates the RMS delay spread, defined as the square root of the second central moment of the power delay profile.   MATLAB Code  clc...

LDPC Encoding and Decoding Techniques

📘 Overview & Theory 🧮 LDPC Encoding Techniques 🧮 LDPC Decoding Techniques 📚 Further Reading 'LDPC' is the abbreviation for 'low density parity check'. LDPC code H matrix contains very few amount of 1's and mostly zeroes. LDPC codes are error correcting code. Using LDPC codes, channel capacities that are close to the theoretical Shannon limit can be achieved.  Low density parity check (LDPC) codes are linear error-correcting block code suitable for error correction in a large block sizes transmitted via very noisy channel. Applications requiring highly reliable information transport over bandwidth restrictions in the presence of noise are increasingly using LDPC codes. 1. LDPC Encoding Technique The proper form of H matrix is derived from the given matrix by doing multiple row operations as shown above. In the above, H is parity check matrix and G is generator matrix. If you consider matrix H as [-P' | I] then matrix G will be...

We select two levels (two different voltage levels) for transmitting modulated message signals. For example, "+5 Volt" (upper level) and "0 Volt" (lower level). To transmit binary bit "1", the transmitter sends "+5 Volts", and for bit "0", it sends no power. The receiver uses filters to detect whether a binary "1" or "0" was transmitted. ...
