Abstract
A system and a method for code division multiple access (CDMA) communication. The system includes fixed terminals communicating with a central base station. The terminals in protection sectors of each sector are configured to employ codes from different sets of codes to overcome potential mutual interference between sectors on account of antenna radiation pattern roll-off. The remaining codes, preferably the majority of the available codes, are used in any one of a plurality of basic sectors, each of which separates the protection sectors of a respective sector. For an even number of sectors in a cell, the available codes are partitioned into three groups, two for the protection sectors and one for the basic sectors. For an odd number of sectors in a cell, the available codes are partitioned into four groups, three for the protection sectors and one for the basic sectors. Protection sectors are relatively narrow but broad enough to counteract the potential mutual interference between sectors.
