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 13):
The communication receiving apparatus according to  claim 12 , wherein the augmentizer-pivorizer unit comprises an augmentizer, and the augmentizer is configured for:\n for each iteration:\n determining an (M\u2212i)-dimensional constraint symbol vector from the linearly-constrained equation according to the given i-dimensional seed symbol vector; \n quantizing the (M\u2212i)-dimensional constraint symbol vector to determine an (M\u2212i)-dimensional seed complementary symbol vector; and \n concatenating the given i-dimensional seed symbol vector and the (M\u2212i)-dimensional complementary symbol vector to form an M-dimensional augmented symbol vector.
