用了MATLAB自带函数,能运行吗? 可以正确运行!那么能不能用自编的函数来代替vitdec函数呢?再来看看AI给出的代码?看看剩余的代码吧!% Additive White Gaussian Noise (AWGN) channelrxSignal = awgn(modulatedSignal, snr, 'measured'); % BPSK demodulation rxBits = rxSignal > 0; % Custom Viterbi decoding ...
This project sought to investigate the performance of TCM in Additive White Gaussian Noise, modelling a mobile wireless channel. To do this, trellis codes are digitally modulated with M-ary PSK and M-ary QAM using computer simulation (MATLAB) and the performance is evaluated when the modulated ...

The additive Gaussian white noise (AGWN) level in real-life images is usually unknown, for which the empirical setting will make the denoising methods over-smooth fine structures or remove noise incompletely. The previous noise level estimation methods are easily lost in accurately estimating them fr...
The FPGA design is based on the System Generator from Xilinx, which is a design tool over Simulink of Matlab. System Generator allows one to design in a fast and flexible way. It uses low level details of the circuits and the functionality of the system can be fully tested. System ...
