Abstract
A Spatial Multiplexing Multiple Input Multiple Output (SM-MIMO) communication system, which generates Q and R matrices through QR decomposing a channel matrix in an array order corresponding to an order of transmission antennas of a signal transmission device, determines a detection order of transmission symbols included in a transmission symbol vector, QR decomposes a reception signal vector and generates the QR decomposed reception signal vector as a transformed reception signal vector, substitutes all of transmittable candidate symbols for a transmission symbol corresponding to a first detection order among the transmission symbols and sequentially removes interference in the transformed reception signal vector, detects candidate symbols of transmission symbols corresponding to a remaining detection order from the interference-removed transformed reception signal vector, combines the detected candidate symbols, detects candidate symbol vectors, and calculates Log-Likelihood Ratio values of bits included in the transmission symbols by using the detected vectors.
