#CMT# #/CMT# The method involves calculating in the frequential domain, sub-carrier by sub-carrier, an extraction of a desired signal for each signal emitted by emission antennas through a transmission channel from signals received on the different reception antennas (RX 0-RX nr-1), where N is greater than or equal to 1. The extraction is carried out in a spatial manner, i.e. for each pair of emission and reception antennas. #CMT# : #/CMT# Independent claims are also included for the following: (1) a detector for a space division multiplexed signal reception device (2) a receiver comprising a detector (3) a transmission system comprising emission antennas, reception antennas, a transmission channel between the emission and transmission antennas and receiver (4) a computer program, on a data medium, comprising program instructions to implement a space division multiplexed signal reception method (5) a digital signal used in a receiver (6) a data medium comprising program instructions to implement a space division multiplexed signal reception method. #CMT#USE : #/CMT# Used for the reception of a space division multiplexed signal transmitted through a transmission channel (claimed) to decode the signal, in a multiple input multiple output (MIMO) system, in a wireless communication system e.g. multi carrier code division multiple access (MC-CDMA) or orthogonal frequency division multiplexed access system or single carrier system, in a time, frequency or code division multiplexing structure, in a hardware elements integrated to an application specific integrated circuit (ASIC), digital signal processor (DSP), programmable logic circuit such as PLD or FPGA, controller, microcontroller and microprocessor and in a memory with a logical code. #CMT#ADVANTAGE : #/CMT# The method permits to improve the performances with the existing linear detection without increasing the detection complexity for the MIMO system. The method allows decoding of the signal with less complexity as it does not require inverse matrix. The extraction enables to process in an individual manner the extracted different signals corresponding to emitted signals, thus permitting to associate finer noise processing. The extraction takes into account the variations of the transmission channel as well as the impact of the extraction of signal on the received signal. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of a space division multiplexed signal reception method.
