MATLAB Code for QPSK Modulation and Demodulation 因为在学习5G物理层，一直很忙，没有时间。最近稍有一点空闲，所以，学习一下算法。QPSK的算法，虽然说我没有完全学透，大致还是懂的。只能一直没时间用MATLAB来研究一下。然后看到这个实例，感觉很好。因为没有中间的AWGN和采样的过程，只讲调制与解调，适

The code snippet provided in the previous section demonstrates how QPSK modulation and demodulation can be implemented using MATLAB. The code generates a random QPSK modulated signal, displays the signal in a scatter plot, and then performs QPSK demodulation to recover the original digital data. The...

Decode a shortened TPC code. Apply QPSK modulation and output the approximate log-likelihood ratio signal obtained from QPSK demodulation. Begin by encoding a random bit vector using 2-D turbo product coding (TPC) with extended Hamming codes and extended BCH codes. Specify (N,K) code pairs and...
