چکیده

Direct-sequence code-division multiple-access (DSCDMA) cellular systems, such as Wideband CDMA (WCDMA), are limited in performance by interference. Several types of Rake Receivers like A-Rake, S-Rake, P-Rake, Adaptive frequency Rake, Time frequency Rake, Conventional MMSE Rake and Adaptive MMSE rake are used for WCDMA. A Beam formerRake receiver can be an effective solution to provide the receivers enhanced capabilities needed to achieve the required performance of a WCDMA system. Beam former-Rake receivers for WCDMA uplink employ three Eigen-Beam forming techniques which based on the Maximum Signal to Noise Ratio (MSNR) and Maximum Signal to Interference and Noise Ratio (MSINR) criteria. In this paper, we have analyzed the performance of Beam-former rake receiver and Adaptive rake receiver for WCDMA.

Analytical Results for BER Performance of MIMO-Rake Receiver in WCDMA System

Abstract – The use of Rake Receiver in Wideband Code Division Multiple Access (WCDMA) system provides a unique and valuable means of combating the adverse effects of short-term multipath fading in mobile radio propagation environments. The transmitted signal bandwidth in WCDMA system is much larger than the coherent bandwidth of the channel, in this case the channel is frequency selective chann...

Adaptive channel equalization in WCDMA downlink in soft handover

Receivers based on channel equalization have proven to be one of the most promising candidates for terminal receivers in wideband code-division multiple-access (WCDMA) downlink. The channel equalizers provide multiple access interference (MAI) suppression, and thus ensure adequate receiver performance even with a high number of active users. However, the suitability of the equalizers to soft ha...
