The BPSK modulation and demodulation represents an important modulation technique in terms of signal power. The BPSK system is simulated using Matlab/Simulink environment and System Generator, a tool from Xilinx used for FPGA (Field-programmable gate-array) design as well as implemented on Spartan ...
MATLAB Online에서 열기 I use BPSK modulator and de-modulator and for error correction i use LDPC. input for LDPC decoder should be soft out put (likelihood) not real value but to calculate this soft bit I have problem. below is my code, how to calculate the soft bit out put a...
