Title:
METHOD AND DEVICE TO GENERATE ZERO CORRELATION ZONE CODE, TRANSMITTING SPREADING CODE AND RECEIVING SPREADING CODE
Document Type and Number:
WIPO Patent Application WO/2008/116413
Kind Code:
A1
Abstract:
A method and device to generate zero correlation zone codes, a method and device
to generate transmitting spreading codes and a method and device to generate
receiving spreading codes are provided, which belong to the field of communication
coding. The method to generate zero correlation zone codes comprises: combining
the original m sequence, i.e. the linear feedback shift register sequence with
the maximum length, and the sequence {1} to be a basic code (102); spreading the
basic code, generating a zero correlation zone code (104). The method to generate
transmitting spreading codes comprises: spreading the basic code generated
by using the original m sequence and the sequence {1}, generating a zero correlation
zone code; inserting non-zero protecting intervals into the zero correlation
zone code, generating a transmitting spreading code.
