METHOD FOR DESPREADING QUADRATURE PSEUDORANDOM NOISE

摘要

FIELD: information technology.;SUBSTANCE: method of despreading quadrature pseudorandom noise involves using data sequences I' and Q' and pseudorandom noise sequences PNI and PNQ to be in every time interval for despreading quadrature pseudorandom noise, continuously extracting 2048 pseudorandom noise signal elements from the pseudorandom noise sequence PNI and each pseudorandom noise sequence PNQ, respectively, time-division demulitiplexing said 2048 pseudorandom noise signal elements, respectively, and obtaining pseudorandom noise sequences PNI' and PNQ', each having length of 1600 pseudorandom noise signal elements; performing a quadrature pseudorandom despreading operation for pseudorandom noise sequences PNI' and PNQ' and data sequences I' and Q' with length of 1600 pseudorandom noise signal elements, which have been input into the time interval and then outputting data sequences I and Q.;EFFECT: reduced complexity of the transmitting part.;11 cl, 7 dwg
