LDPC Coding with PSK modulation in an AWGN channel Description LDPC Coding with PSK modulation in an AWGN channel Most of the functions are built in matlab functions found in the comm. toolbox. These can also be easily configurable in the code to meet your requirements. In the given code, set the SNR, codeRate, modulation order (psk) and Number of frames to be simulated. Please feel free to contact me and let me know your comments.

VITERBI DECODING ALGORITHM SIMULATION IN MATLAB CODE

用线形天线阵（ULA）进行波达方向估计，代码、注释与说明(Estimate the direction of arrival (DOA) by MUSIC/ESPRIT methods using ULA. Matlab codes and documents included.)

说明：  通带截止频率 =2 4k rad/s，阻带截止频率 =2 8k rad/s，通带波纹系数 =0.3dB, 阻带波纹系数 =50dB,采样频率fs=20000Hz。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter.)
