With the successive cancellation of three subsidies and some of the preferential from the CPC, the remaining body faced tough and severe situations.

Finally, a successive interference cancellation (SIC) scheme is proposed combined with minimum mean square error (MMSE) detection. Its performance is superior to simple SIC or MMSE detector.

With an eye to the character of the ordered successive interference cancellation (OSIC) detector based on restructured channel matrix, the as is achieved by optimizing the poor sub signal stream.
