Base station transceiver design in a digital wireless local loop system

During the past ten years the mobile radio communications industry has significantly grown. The miniaturization technologies have allowed smaller and smaller portable terminal radio equipment. People throughout the world have been adhering to the wireless communications methods and services mainly of the public cellular mobile network. The digital cellular mobile networks already implemented all over the world such as for instance, the GSM, PDC and IS-95 provide a very low bit rate which is inefficient for data and video services. Higher bit rate mobile networks are now under research and development. This paper describes a base station transceiver for a higher bit rate digital wireless local loop communications system
