A low-complexity analog linear coding scheme for transmitting asymptotically WSS AR sources

In this letter, we give a low-complexity analog linear coding scheme for transmitting finite-length data blocks of asymptotically wide sense stationary (AWSS) autoregressive (AR) sources through additive white Gaussian noise (AWGN) channels
