A new approach to BSOFDM - parallel concatenated spreading matrices OFDM

This paper proposes a new approach to block spread OFDM called parallel concatenated spreading matrices OFDM (PCSM-OFDM). While BSOFDM improved the overall BER performance on OFDM in frequency selective channels, this new approach further improves the BER of BSOFDM by a 3 dB gain. This is achieved through increasing the diversity of the transmitted samples by concatenating two spreading matrices in parallel to BSOFDM.
