Abstract :
A generalized model is presented for analyzing a DS/CDMA picocellular mobile radio system. The proposed model employs microscopic diversity of RAKE receivers. Fading, multiple access interference (MAI), sectorization, sectorization imperfection and voice activity monitoring are considered. The signal to noise plus interference (SINR) and average probability of error are derived. The analysis quantifies the effects of MAI and sectorization imperfection on the system performance; shows that MAI can be reduced by sectorization, voice activity monitoring and confirms that multipath fading can be mitigated by microscopic diversity of RAKE receivers
