This paper presents a link adaptation strategy for non-binary LDPC code over a time-variant frequency-selective channel. The algorithm is based first on the adoption of waterfilling technique to wisely adapt the transmitted power. It is shown that as long as best subchannels are identified with the waterfilling algorithm, an equal power distribution can be applied with performance comparable to the...
In the present wireless scenario, transmit diversity has become one of the key contributing technologies. Analytical estimations of bit error rate (BER) can be obtained with space time transmit diversity (STTD). The desired user's BER performance improves as fading of interfering signal decreases. Nakagami-m fading is becoming more prevalent in performance analysis and other studies related to mobile...
