comparison of BER performance for mapping of turbo coding with 16QAM 64QAM 128QAM

Two different types of measurement matrices: predefined and random measurement matrices were studied and tested using MATLAB. The speech signal was reconstructed without losing important information in order to achieve an increase in the data rates. After multiple simulations
