AN2253, Channel Estimation for a WCDMA Rake Receiver
The third-generation universal mobile telecommunications system (UMTS) uses direct-sequence code division multiple access (DS-CDMA) to transmit data. DS-CDMA is well suited to transmit data over the multipath fading channel. The high signal bandwidth for the WCDMA system (5 MHz) allows the received signal to be split into distinct multipaths with high resolution. For the first generation of UMT...
متن کاملA Novel Multipath Interference Cancellation Scheme for RAKE Channel Estimation
A novel channel estimation scheme is proposed for a RAKE receiver operating in the downlink of a mobile communication scenario. The approach is an extension of the well known Wiener channel estimator and partly cancels multipath interference, with the additional advantage of being able to cope with physically closely spaced multipaths which arise, for example, in an indoor scenario. It is demon...
متن کاملAverage channel capacity for generalized-selection combining RAKE receivers
RAKE reception has been considered as an effective way to anticipate multipath signal fading in direct sequence code division multiple access (DS-CDMA) communications systems. Common diversity techniques used in conventional fingered RAKE receivers are maximal-ratio combining (MRC) and equal-gain combining (EGC). Conventional fingered RAKE receivers offer increased complexity, since the number ...

متن کاملchannel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
