Title Proper : ADVANCED RECEIVERS FOR WCDMA DOWNLINK
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : In this master's thesis, the issue of signal detection in the downlink of Code Division Mul-tiple Access (CDMA) is addressed. First, we observe the CDMA downlink in a frequency-selective slow fading channel as a linear combination of convolved independent symbolsequences and develop a higher order statistics (HOS) based novel symbol estimationmethod. We call this method as Blind Multiuser Seperation (BMUS), which inherentlybenefits from quasi-orthogonality of the user spreading codes and the independence amongtransmitted user, and evaluate its applicability in a "short code" limited knowledge CDMAscenario. Later we develop 3G WCDMA downlink specific chip-level space-time equaliz-ers capable of providing uncoded BER of 5....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
