Abstract:
1. Detection process for a receiver of a wireless communication system based on Multiple-In-Multiple-Out antennas, said receiver processing observations symbols y derived from symbols x transmitted by an emitter through a channel H; said process comprising: a preprocessing which only depends on the channel H, said preprocessing involving: a loading phase comprising a linear LRA-Minimum-Mean-Square-Error equalization applied on said symbols y in accordance with the result of said lattice reduction for the purpose of generating a value {tilde over (z)} wherein said process further involves the steps of: performing a neighborhood search with a search center being equal to the result determining the K-Best symbols in accordance with a Partial Euclidean Distance (PED) defined in accordance with the following formula: detecting each layer and with the result of said detection performing an update of the search center so as to perform detection of the next layer; multiplying the estimated value performing a quantization in the original constellation comprising a dictionary of symbols presumably known to the receiver so as to generate the estimated value
