Pre-FFT and post-FFT adaptive antenna array for OFDM transmission over cognitive radio network

Pre-FFT and post-FFT adaptive antenna array for OFDM transmission over cognitive radio network

This paper presents the joint interference cancellation and equalization for space-time block coded (STBC) orthogonal frequency division multiplexing (STBC-OFDM) transmission over underlay cognitive radio network. In this work, pre- and post-FFT adaptive antenna array is employed at secondary user r...
