Code Selection Method for Downlink MC-CDMA Over Frequency-Selective Fading Channel
Chin-Kuo Jao, Yu‐Chieh Cheng, Shyue‐Win Wei · IEEE Transactions on Vehicular Technology · 2008
A spreading code-allocation procedure using simple least squares (LS) channel estimation is presented to reduce multiple-access interference (MAI) in downlink multicarrier code-division multiple-access (MC-CDMA) systems. The spreading codes chosen by the proposed method are in a consistent sequence.
