It is foreseen that the next generation of cellular network would integrate the relaying or multihop scheme. In a multihop cellular architecture, the users are not only able to communicate directly to the base station (BS) but can also use some relay stations to relay their data to the BS. These relay stations can either be the users' mobile station (i.e. mobile relay station) or some low cost station...
This paper presents a performance evaluation in terms of bit error rate (BER) of a 26 GHz-band ultra-wideband (UWB) communication system through measurement-based simulation. We measured real channel responses in an office to obtain responses for use in simulations. The simulation results demonstrate that the 26-GHz-band UWB system can achieve high-speed data transmission of 500 Mbps or more, in and...
The next step in the evolution of UMTS is the Enhanced Uplink or high speed uplink packet access (HSUPA), which is designed for the efficient transport of packet switched data. One of the major novelties is the relocation of the scheduling control from the RNC to the NodeB which enables a faster reaction to cell load and radio condition variations. Our contribution is an analytic modelling approach...
The spatio-temporal array-receiver (STAR) decomposes generic wideband CDMA channel responses across various parameter dimensions (e.g., time-delays, multipath components, etc...) and extracts the associated time-varying parameters (i.e., analysis) before reconstructing the channel (i.e., synthesis) with increased accuracy. This work verifies the performance of STAR by comparing the results achieved...
