This paper presents an analytical method for estimation of sectorization gain in CDMA cellular systems. Non-ideal antenna radiation patterns are investigated in order to identify the factors which limit the sectorization gain. These include...

In this paper, we propose reverse link transmission (both traffic and pilot) to be gated 50% of the time for 1/8 rate speech transmission and show that significant talk time and reverse link capacity improvement can be achieved out of this ...

In this paper, we analyse the MAI (multiple access interference) characteristics of mixed services (voice, circuit data, and packet data) in UMTS FDD-WCDMA mode. According to the various traffic and the system parameters [ETSI], the combina...

Wideband CDMA has been selected as the access technique for the next generation communication system. Consequently, it has received a significant amount of attention in provision of advanced algorithms for improved performance. Accurate pow...

Performance of a reverse link wideband CDMA cellular system with fast closed-loop power control is studied in this paper. The channel is modelled as frequency selective fading. The probability of bit error, P/sub c/, is used as the performa...

Power control is an important issue in the capacity of DS-CDMA cellular systems to tackle the near-far problem, co-channel interference and varying signal strength in fading channels. In this paper, we propose an adaptive signal-interferenc...

Knowledge of the radio channel conditions help in improving the performance of the receiver as well as in maintaining the quality of service required by different applications supported by the third generation wireless systems. Power contro...

The CDMA technology used in UMTS relies on accurate power control techniques, not only for maximising the battery life of mobile terminals and maintaining signal quality, but also as an important means of optimising system capacity by contr...

The third generation (3G) of mobile communications is approaching fast and networks based on 3G technology will be operational in the next few years in the major European countries. They will inherit system characteristics both from traditi...

Interoperation of 2G and 3G networks will be an important issue when both kinds of networks will exist in parallel and need to interwork with each other. Among other things, this implies that 2G subscribers should be able to access 3G netwo...
