Engineering Mini Project Ideas

1. Analog Communication Systems

Explore the foundations of wireless transmission by focusing on analog modulation techniques such as Frequency Modulation (FM) and hardware implementations like Walkie-Talkies.

2. Performance Analysis of ASK, FSK, and PSK

This project focuses on the relative performance of digital modulation schemes. Analyze Amplitude, Frequency, and Phase Shift Keying through MATLAB and Simulink simulations.

Project Scope: Create an introduction to ASK, FSK, and PSK. Compare these systems by generating Bit Error Rate (BER) vs. SNR graphs, evaluating bandwidth efficiency, and noise resistivity.
Reference: ASK, FSK, and PSK Definition and Comparison.

3. M-ary Modulation & Modern Techniques

Investigate modern modulation schemes like M-ary QPSK and QAM. As data demands increase, understanding the trade-off between constellation density and noise handling is critical.

The goal of this project is to determine the performance limits of QAM vs QPSK in high-interference environments. You should analyze Bit Rate, Baud Rate, and Complexity for various constellation sizes to see where QAM outperforms QPSK in real-world scenarios.

Rayleigh vs Rician Fading (with MATLAB + Simulator)

  In Rayleigh fading , the channel coefficients tend to have a Rayleigh distribution, which is characterized by a random phase and magnitude with an exponential distribution. This means the magnitude of the channel coefficient follows an exponential distribution with a mean of 1. In Rician fading , there is a dominant line-of-sight component in addition to the scattered components. The channel coefficients in Rician fading can indeed tend towards 1, especially when the line-of-sight component is strong. When the line-of-sight component dominates, the Rician fading channel behaves more deterministically, and the channel coefficients may tend towards the value of the line-of-sight component, which could be close to 1.   MATLAB Script clc; clear all; close all; % Define parameters numSamples = 1000; % Number of samples K_factor = 5; % K-factor for Rician fading SNR_dB = 20; % Signal-to-noise ratio (in dB) % Generate complex Gaussian random variable for Rayleigh fading channel h_r...

Theoretical vs. simulated BER vs. SNR for ASK, FSK, and PSK (MATLAB Code + Simulator)

📘 Overview 🧮 Simulator 💻 Theoretical Code 📊 Simulated Code 📚 Resources Overview BER vs. SNR denotes how many bits in error are received for a given signal-to-noise ratio, typically measured in dB. Common noise types in wireless systems: 🚀 1. Additive White Gaussian Noise (AWGN) 🌊 2. Rayleigh Fading AWGN adds random noise; Rayleigh fading attenuates the signal variably. A good SNR helps reduce these effects. Bit Error Rate (BER) Equations BER formulas for ASK, FSK, and PSK modulation schemes. ASK BER = 0.5 × erfc(0.5 × √SNR) FSK BER = 0.5 × erfc(√(SNR / 2)) PSK BER = 0.5 × erfc(√SNR) erfc / Q-function (Click here) Live BER S...
