Two of the major second generation standards, GSM and TDMA/1361, have built the foundation to offer a common global radio access for data services. Through use of a common physical layer, EDGE (Enhanced Data rates for GSM and TDMA/136 Evolution), both standards will have the same evolutionary path towards providing third-generation services. EDGE is currently subject to standardization in TIA T...

BellSouth has proposed a modification to the IS-136 digital cellular standard, which they refer to as Advanced Vocoder Idle Slot Exploitation (ADVISE), in which base stations can transmit auxiliary coded (redundant) bits on otherwise unused time slots to assist certain subscriber units (SUs). In this master's thesis, we investigate two aspects of ADVISE: 1) adaptive redundancy schemes by which ...

In this paper, we investigate the performance of transmit diversity technique operating in IS-136 T D M A systems where the Doppler frequency can be as high as 184Hz. Transmit diversity transforms a pat fading channel into a frequency selective fading channel, thus we use finite length decision feedback equalizers to estimate the desired signal at the receiver. The channel parameters are traine...

BACKGROUND A growing number of online pharmacies have been established worldwide. Among them are numerous illegal websites selling medicine without valid medical prescriptions or distributing substandard or counterfeit drugs. Only a limited number of studies have been published on Internet pharmacies with regard to patient safety, professionalism, long-term follow-up, and pharmaceutical legitim...

Using apoE phenotyping by immunoblotting and apoE genotyping we identified four heterozygous carriers of a rare apolipoprotein (apo) E2 variant, apoE2 (Arg 136 → Cys). ApoE2 (Arg 136 → Cys) was not distinct from apoE2 (Arg 158 → Cys) by phenotyping, but produced a unique pattern of bands on Cfo I restriction typing of a 244 bp apoE gene fragment. Two of the four apoE2 (Arg 136 → Cys)/3 heterozy...
