System and method for optimizing Walsh code assignments

摘要

A wireless communication system is disclosed, including a network and a plurality of base stations coupled to the network, wherein each of the base stations are adapted to transmit only a Pilot channel information, one or more Paging channel information, and a Sync channel information using a first group of adjacent Walsh codes W_iⁿ to W_i+jⁿ, where i and j are integers, and n is the length of the Walsh codes. In the wireless communication system, the base station may be further adapted to transmit traffic channel information using a second group of adjacent Walsh codes W_i+j+lⁿ to W_n-1ⁿ. Alternatively, the base station may be further adapted to transmit traffic channel information using a second group of adjacent Walsh codes W₀ⁿ to W_i-1ⁿ. Alternatively, the base station may be further adapted to transmit traffic channel information using a second group of adjacent Walsh codes W_int(j/2+)^n/2 to W_n/2-l^n/2 or W₀^n/2 to W_int(i/2-l)^n/2.
