We propose and evaluate the performance of a cascaded THP and BD system (THP-BD) for a MIMO downlink in which BD is used to mitigate multi-user interference and THP is used to mitigate spatial interference. We show that at moderate to high SNR, the cascaded THP-BD system achieves the same error performance as the system employing THP on a multi-user MIMO (MU-MIMO) downlink. Also, symbol error rate...
Multi-antenna-based multi-input multi-output (MIMO) communicationsbecomes the next revolution in wireless data communications. MIMO has gone through the adoption curve for commercial wireless systems to the point that today, all high throughput commercial standards, i.e. WiMax, Wi-Fi, cellular, etc., have adopted MIMO as part of the optional. This paper is to present our investigations of the behaviors...
The 3GPP Long Term Evaluation project is looking at the possibility of application of OFDM in the downlink, in order to support a high downlink data rates - 100 Mbps. In this evolved UTRA, a fast cell search is necessary because besides considering the 900-MHz frequency band GSM spectrum and the WCDMA-3G spectrum; an additional spectrum is to be used. Multiple transmission bandwidths from 1.25 to...
