IEEE/Sarnoff Symposium on Advances in Wired and Wireless Communication, 2005..
In February of 2002, the FCC liberated the airwaves and laid the regulatory framework for the unlicensed use of approved UWB devices over the 3.1-10.6 GHz bands. By transmitting very low power signals across several gigahertz of the frequency band, g

Proceedings of GLOBECOM'96. 1996 IEEE Global Telecommunications Conference.
This paper studies diversity combining techniques in the GSM based systems. A pre-detection maximal-ratio diversity receiver for GSM is presented. It is an optimum diversity demodulator for band-limited channels with Gaussian noise and intersymbol in

Proceedings of ICUPC - 5th International Conference on Universal Personal Communications.
This paper addresses the problem of allocating frequencies in a GSM-based home base station (HBS) system. A novel solution called total frequency hopping (TFH) is presented in order to overcome the frequency allocation and the inter-HBS synchronisati

This paper presents a method to provide 14.4 kbit/s service by a single TDMA slot in the GSM system. By modification in the puncturing scheme used in the GSM channel coding the air interface speed can be enhanced to 14.4 kbit/s. The reduction in erro
