Although the broadcast schemes for MIMO systems with CSI at the transmitter have been extensively studied (see [25-26]), comparison studies on the symbol error rate (SER) and bit error rate (BER) performance analyses and spectrum utilization for CR network transmission inspired by DPC over fading channels do not exist in the technical literature.
Rayleigh Fading Channel. In this part, we will compare the analytical expression of the BER performance in the Rayleigh fading channel to simulation results in the two following cases:
Finally, by the cooperative MRC detection at the destination node D in (9), the proposed ILAR scheme can match the CSI in all of the channels and thus obtain better performance over the traditional schemes of the AF, the DF, and the SDF protocols under the premise of Rayleigh fading channel with the independent and identically distributed (i.i.d.) AWGN parameters.

The improved classification capability and robustness of the proposed system for real-time underwater signals in the fading channel conditions make the system acceptable for underwater naval applications like monitoring, target detection, and classification.
