Title:
METHOD FOR DESPREADING ORTHOGONAL PSEUDORANDOM NOISE
Document Type and Number:
WIPO Patent Application WO/2008/067689
Kind Code:
A1
Abstract:
A method for despreading orthogonal pseudorandom noise includes the following steps: inputting data sequences I' and Q', and inputting pseudorandom noise sequences PNI and PNQ to be despreaded; in every timeslot, respectively continuously extracting 2048 symbols from the pseudorandom noise sequence PNI or the pseudorandom noise sequence PNQ, respectively demulitiplexing said 2048 symbols, and obtaining pseudorandom noise sequences PNI' and PNQ' which both are 1600 symbols; performing orthogonal pseudorandom despreading operation for pseudorandom noise sequences PNI' and PNQ' and data sequences I' andQ' which has been input and are 1600 symbols, and then outputting data sequences I and Q. According to present invention, the sequences that were input to be performed orthogonal pseudorandom noise despreading were processed, therefore the system transmission requirement is satisfied, and the complexity of the transmitting end is reduced.
