Abstract:
1. A turbo-reception method of receiving a signal from N transmitters where N is an integer equal to or greater than 2, comprising the steps of calculating a channel value h determining a soft decision transmitted symbol b′ using the channel value h where B′ ( k )=[ b′ T ( k+Q− 1) . . . b′ T ( k ) . . . b′ T ( k−Q+ 1)] T b′ ( k+q )=[ b′ 1 ( k+q ) b′ 2 ( k+q ) . . . b′ N ( k+q )] T q=Q− 1 . . . − Q+ 1 q≠ 0 b′(k) having a zero element at an n-th position and [ ] T representing a transposed matrix; subtracting the interferenced component H·B′(k) from a received matrix y(k) to obtain a difference matrix y′(k) where using the channel matrix H or a reference signal to determine an adaptive filter coefficient w and filtering the difference matrix y′(k) with the adaptive filter coefficient w
