An Improved Base Station Modulator Design for a CDMA Mobile System

A Base Station Smart Antenna System for CDMA Cellular

Adaptive antenna arrays can increase the capacity of wireless mobile communication systems by reducing cochannel interference. This thesis reviews current base station technology and examines the possibility of implementing an adaptive phased antenna array at a cellular CDMA base station. It is seen that a computationally simple beamforming system and direction-of-arrival estimator can signific...

PV-solar / Wind Hybrid Energy System for GSM/CDMA Type Mobile Telephony Base Station

This paper presents the design of optimized PV-Solar and Wind Hybrid Energy System for GSM/CDMA type mobile base station over conventional diesel generator for a particular site in south India (Chennai). For this hybrid system ,the meteorological data of Solar Insolation, hourly wind speed, are taken for Chennai (Longitude 80 ο .16’and Latitude 13 ο .5’ ) and the pattern of load consumption of ...

Base Station System Configurations for Future Universal Mobile Telecommunication Systems

This paper presents a study of base station system configurations for the Universal Mobile Telecommunication System (UMTS). The base station system (BSS), being the interface between the mobile terminal and fixed network, should be capable of handling a huge amount of traffic, mobility, and a high signaling load which is expected in the UMTS. Several functions that should be supported by BSS ar...

Dimensioning of communication links for base-station and MSC interconnection in CDMA mobile communication systems

In CDMA mobile communication systems, voice is encoded and packaged in variable length packets that are transported between the mobile station and the switching center. While the packetization provides a great flexibility in resource allocation, it poses a QOS challenge on voice. In this paper, we discuss link dimensioning for a typical CDMA system. We consider a communication link connecting a...
