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

EURASIP Journal on Advances in Signal Processing, 2010 A recursive maximum-likelihood (RML) algorithm for channel estimation under rapidly fading channel and colored noise in a multicarrier code-division multiple-access (MC-CDMA) system is proposed in this paper. A moving-average model with exogenous input (

Blind channel estimation for the uplink of MC-CDMA systems with timing offset
Tongxin xuebao, 2007 A new blind channel estimation scheme was proposed for the uplink of multicarrier code-division multiple ac-cess（MC-CDMA） systems with timing offset（TO）.The scheme can cancel TO effects on the channel estimation,and thus work well without synchronizing ...

PAPR reduction in SFBC MIMO MC-CDMA systems via user reservation
EURASIP Journal on Advances in Signal Processing, 2011 The combination of multicarrier code-division multiple access (MC-CDMA) with multiple-input multiple-output technology is attractive for broadband wireless communications. However, the large values of the peak-to-average power ratio (PAPR) of the signals

Successive interference cancellation receiver algorithms for uplink STBC coded MC-CDMA systems
Tongxin xuebao, 2006 A QR decomposition based and a minimum mean square error （MMSE） based successive interference cancel-lation receiver algorithms were proposed for the uplink of space-time block coded multi-carrier code division multiple access （MC-CDMA） systems.
