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 18):
The communication receiving apparatus according to  claim 17 , wherein the symbol detector is configured for:\n for each of the M branch estimations:\n determining an iteration variable as i, which is a positive integer; \n constructing an M-dimensional seed symbol vector according to a corresponding 1-dimensional seed symbols; \n splitting the M-dimensional seed symbol vector into (M\u2212i) (i+1)-dimensional seed symbol vectors; \n determining (M\u2212i) pivoting symbol vectors according to the (M\u2212i) (i+1)-dimensional seed symbol vectors, respectively; \n selecting one of the (M\u2212i) pivoting symbol vectors as an estimated result; and \n comparing the estimated result with another estimated result selected in a previous iteration.
