ABSTRACT:
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 Winto Wi+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 Wi+j+1nto Wn−1n. Alternatively, the base station may be further adapted to transmit traffic channel information using a second group of adjacent Walsh codes W0nto Wi−1n. Alternatively, the base station may be further adapted to transmit traffic channel information using a second group of adjacent Walsh codes Wint(j/2+1)n/2to Wn/2−1n/2or W0n/2to Wint(i/2−1)n/2.
