Abstract :
Interference reduction is the key factor in cellular wireless point-to-multipoint (PMP) network design; therefore antenna and frequency sectoring solutions are commonly applied. We consider code-division multiple access (CDMA) with the aid of a multiuser receiver to improve the interference suppression capability. Code sectoring solutions provided by CDMA are introduced for different antenna, frequency and polarization sectoring combinations.
