Differential space-time modulation schemes for smart antenna aided generalized multicarrier DS-CDMA systems [PDF]

, 2006
—Differential space-time modulation (DSTM) schemes were proposed for detection without any knowledge of the Channel State Information (CSI), which is an attractive feature in the presence of fast fading channels, where accurate channel estimation is a ...

Exact BER Performance of Asynchronous MC-DS-CDMA over Fading Channels

, 2010
In this contribution an accurate average Bit Error Rate (BER) formula is derived for MC-DS-CDMA in the context of asynchronous transmissions and random spreading sequences. We consider a flat Nakagami-m fading channel for each subcarrier. Our analysis is
