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 5):
The method for detecting transmit symbols according to  claim 4 , wherein the step of pivoting the M-dimensional augmented symbol vector to obtain the pivoting symbol vector with M dimensions comprising:\n determining an iteration variable; selecting an index set according to the iteration variable; determining a 1-dimensional constraint symbol from the linearly-constrained equation according to an (M\u22121)-dimensional seed symbol vector, wherein the (M\u22121)-dimensional seed symbol vector is determined from the M-dimensional augmented symbol vector according to the index set; quantizing the 1-dimensional constraint symbol to determine a 1-dimensional seed complementary symbol; concatenating the (M\u22121)-dimensional seed symbol vector and the 1-dimensional seed complementary symbol to form a preliminary pivoting symbol vector; determining whether the preliminary pivoting symbol vector is equal to the M-dimensional augmented symbol vector; setting the pivoting symbol vector as the preliminary pivoting symbol vector in response to the preliminary pivoting symbol vector being equal to the M-dimensional augmented symbol vector for M consecutive iterations; and replacing the M-dimensional augmented symbol vector by the preliminary pivoting symbol vector in response to the preliminary pivoting symbol vector being not equal to the M-dimensional augmented symbol vector for any iteration.
