Abstract:
A communication receiving apparatus and a method for detecting transmit symbols are provided. In the method, received signal and channel state information corresponding to the received signal are obtained. A modified Least-Square (LS) estimation according to the received signal and the channel state information is calculated. The modified LS estimation is defined as min min w   Aw  2 which subjects to a linearly-constrained equation C H w=x−x ls , C is a constraint matrix which is a matrix multiplication of a matrix A and the channel state information matrix H, w is a variable vector, x is a vector of a transmit symbol, and x ls  is a LS solution according to the received signal and the channel state information. The transmit symbol is determined according to the solution of the modified LS estimation. The embodiment of the disclosure is applicable to any digitally modulated communication systems, including but not limited to Multiple Input Multiple Output (MIMO) communication systems.

Claim (Index 4):
The method for detecting transmit symbols according to  claim 3 , after the step of forming the M-dimensional augmented symbol vector, the method further comprising:\n pivoting the M-dimensional augmented symbol vector to obtain a pivoting symbol vector with M dimensions, wherein an (M\u22121)-dimensional seed symbol vector is used as any combination of (M\u22121) elements of the pivoting symbol vector, a 1-dimensional seed complementary symbol is used as remaining 1-element of the pivoting symbol vector.
