Abstract

In this study, the ${\pi}/4$ shift QPSK(quadrature phase shift keying) with NEC(nonredundant error correction) on the multipath channel can detect the burst error as well as random error one by using the second and L-th order phase difference. Therefore, the BER(bit error rate) performance in ${\pi}/4$ shift QPSK is more improved than that of the ${\pi}/4$ shift QPSK without NEC structure. Also, this performance become a bit better in Rayleigh fading channel.
