Embodiment Construction
[0032] In order to clearly illustrate the new invention, firstly the prior art MMSE-OSIC 2 The method is introduced, and then the detection method of the present invention is described accordingly.
[0033] Suppose N T xN R The MIMO system can be expressed as:
[0034] y=Hx+z (1)
[0035] in y = [ y 1 y 2 · · · y N R ] T , Yes (N R ×1)-dimensional received signal vector; N T is the number of transmit antennas, N R is the number of receiving antennas.
[0036]
[0037] is the MIMO channel response; x = [ x 1 x ...
