Abstract :
A max-log-MAP detector based on the sphere decoder is proposed and is shown to provide significant complexity reduction compared to the brute-force method for an equivalent channel coded BER performance. The algorithm is analysed for multiple antenna systems where the performance is compared to a list sphere decoder with bounded complexity for practical implementation.
