SYSTEMS AND METHODS FOR ACHIEVING REDUCED INTER-SECTOR PILOT INTERFERENCEN IN A MOBILE COMMUNICATION SYSTEM

摘要

The pilots of a wireless system are arranged to reduce inter-sector interference by establishing a systematic assignment of pilots across the system. In one embodiment, the pilots are differently coded and directionally positioned within a cell such that the same pilot from adjacent cells do not overlap. In one embodiment, Walsh codes are used to create the differently coded pilot signals.
