Abstract: A symbol detection method and an apparatus for MIMO spatial multiplexing system are provided to reduce total elapse operation quantity by reducing the number of calculation relating to modulation level through equation deformations. A channel response queue heat exchanger(210) successively detects a transmission symbol from each transmission antenna. A channel matrix decomposition unit(220) accepts the signal outputted from the channel response queue heat exchanger and disassembles the signal to an unitary matrix and upper triangular matrix. An unitary matrix multiplication part(230) multiples the Hermitian matrices of the unitary matrix at a received signal vector. A symbol removal part(240) removes influence by the symbol transmitted from the first transmission antenna from the received signal. A symbol combining part(250) detects a symbol of a second transmission antenna. A tentative decision part(260) estimates a candidate transmission symbol vector from the received signal. AN Euclidean distance calculation unit(270) calculates the Euclidean distance by using the candidate transmission symbol vector, channel matrix and received signal vector. An LLR generating unit(280) calculates LLR from the calculated Euclidean distance.
