Presumption of the channel impulse response which uses singular value decomposition

摘要

(57) Abstract As for this invention, it relates to the presumption of CIR (channel impulse response) and SINR (signal anti- interference and noise ratio) in the CDMA receiver. In detail, as for this invention, channel impulse response (CIR) of the communication system, for example, it relates to the manner which decides CIR of the radio channel of digital mobile radio network (GSM network). Especially, this invention, although the known training sequence is received, being based, relates to deciding CIR. And, this invention relates to also application to the interference hitting turning off and use to the CDMA receiver. This invention, it is achieved from the implementation that the matrix which is obtained by network analysis to the diagonal matrix first it can convert, it can lighten the problem which is related the matrix which is obtained and with that to known technology by reversing. Furthermore, this invention, the side lobe is removed until, or in order for those almost to stop influencing, multiplies the numerical value which is decreased to the inverse number of eigen value in the reversal matrix.
