Abstract :
In this paper, we describe a hybrid ZF-SD (zero-forcing and sphere decoding) algorithm. The basic idea is to reduce the dimensionality of decoding via pre-decoding and cancellation of those symbols that can be quickly and reliably detected. The proposed algorithm shows the BER performance similar to SD (sphere decoding) but with very lower computational complexity than SD
