发明名称 Orthogonal frequency division multiplexing signal receiving method for e.g. telecommunication network, involves generating composite signal by summing up signals received respectively on antennae and weighted by coefficients
摘要 #CMT# #/CMT# The method involves determining groups of weighting coefficients so as to increase an error value for each block, via a threshold value. Each block is emitted between reference symbols of the emitted block and symbols obtained using symbols received on antennae at positions of reference symbols corresponding to blocks emitted and associated coefficients. The weighting coefficients are obtained for other symbols of a frame. A composite signal is generated by summing up the signals received respectively on the antennae and weighted by the coefficients. #CMT#USE : #/CMT# Used by a reception device of a telecommunication system such as telecommunication network, orthogonal frequency division multiplexing (OFDM)/4quadrature amplitude modulation (QAM) type, OFDM type, OFDM/isotrophic orthogonal transform algorithm (IOTA) type and OFDM/offset quadrature amplitude modulation (OQAM) type modulation based transmission network, for receiving an OFDM signal in the telecommunication network (all claimed), where the system is used for receiving signals on a set of antennae. #CMT#ADVANTAGE : #/CMT# The method allows to improve the reception of the orthogonal frequency division multiplexing signal in a better manner. The generation of the composite signal allows to increase signal/noise ratio related to the generated composite signal in a better manner. The determination of the weighting coefficients and the generation of the composite signal permit to reduce the signal/noise ratio related to the generated composite signal in the case where noises affect the signals received by the antennae are correlated, thus allowing to reduce the impact of interferences. The method can be implemented in a simple, easy and effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows the main stages of an orthogonal frequency division multiplexing signal receiving method. `(Drawing contains non-English language text)`.
