Abstract
We propose a double layer sphere decoder (DLSD) for under-determined MIMO systems with fewer receive antennas than transmit antennas. This decoder can reach the maximum-likelihood decoding performance with less complexity. We further propose an adaptive DLSD that adjusts the initial squared search radius C according to the SNR adoptively. Simulation results show that both DLSDs have far less complexity than the existing GSDs.
