Digital data transmission system over the Gaus noise channel using a 16-QAM modulator, hamming source encoding, and turbo channel encoding

In this study, the author built and evaluated the performance of a digital data transmission system over a Gaussian noise channel.This system uses components like the 16-QAM modulator and demodulator, hamming source encoding and decoding, and turbo channel encoding and decoding.The 16-QAM modulator is a digital signal modulation method that allows multiple bits to be transmitted through a single symbol.It helps optimize bandwidth and transmission speed.Hamming source encoders help improve noise immunity by detecting and correcting bit errors during transmission.This ensures data integrity.By using independent codes and combining information from received signals, Turbo channel coding improves channel performance.The performance evaluation of the system is conducted through bit error rate calculation and analysis.The results show that the proposed system has the ability to improve transmission performance and anti-interference ability.
