Blind channel estimation for the uplink of MC-CDMA systems with timing offset

open access: yesTongxin 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

open access: yesEURASIP 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

Adaptive Channel-Tracking Method and Equalization for MC-CDMA Systems over Rapidly Fading Channel under Colored Noise

open access: yesEURASIP 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 (
