Relationship Between Throughput and Bit Error Rate for Enhanced Type-II Chase Combining HARQ Mechanism
MATLAB simulation implementation analyzing the throughput vs. bit error rate relationship for an improved Type-II selective repeat HARQ mechanism. The simulation features simplified encoding/decoding processes: simulating erroneous bits probabilistically based on BER, with receiver-side error detection based on correctable error thresholds. Each transmitted codeword undergoes error checking using bit error count information - error-free codewords are accepted while erroneous ones trigger retransmission. The algorithm employs an alternating transmission scheme (via alternate value) between information codewords and parity codewords. When parity codewords arrive, the combined codeword (original + parity) undergoes error correction capability verification - successful correction leads to acceptance, otherwise retransmission is requested.

Bit Error Rate Comparison with and without Channel Coding Technology
This program implements a complete digital communication system using 16QAM modulation, where a binary source is processed through (7,4) cyclic code for channel coding. The signal undergoes baseband modulation with a raised-cosine roll-off filter before upconversion to a high-frequency channel. Gaussian white noise is added to simulate channel conditions. The receiver employs matched filtering for demodulation, generates constellation diagrams, uses minimum Euclidean distance decoding for decision making, and performs channel decoding. The implementation compares bit error rates with and without channel coding through comprehensive simulation.
Simulation Using the rayleighchan Function
When simulating with the rayleighchan function, it is essential to perform phase compensation at the final stage (a critical observation noted by the advisor). The procedural steps involve: generating random sequences, creating a Rayleigh fading channel, modulating the signal, retaining channel characteristics, transmitting the signal through the channel, applying phase compensation, adding Gaussian noise, demodulating the signal, calculating simulated bit error rate (BER), computing theoretical BER, and plotting BER curves in distinct colors for comparative analysis.
