Performance Analysis of ZF Pre-Coder and Extended Joint Channel Estimation Method in Downlink CDMA with HPA
In the down link scenario of code division multiple access (CDMA) systems, multi user detectors (MUDs) such as linear de-correlating detector (LDDs) provide satisfactory symbol error rates (SERs) at the expense of much increased complexity, they require all active users’ spreading sequences, which is impractical from privacy point of view. To overcome this impracticality, a simple matched filte...

متن کاملEstimation of Time-Varying Wireless Channels and Application to the UMTS W-CDMA FDD Downlink
In this paper we consider the estimation of mobile channels that are modeled as autoregressive processes with a bandwidth commensurate with the Doppler spread. Pilot based estimation leads to brute FIR channel estimates on a slot by slot basis. These estimates are then refined by Wiener filtering across slots that performs the optimal compromise between temporal decorrelation due to Doppler spr...
متن کاملA Tree-Structured Blind Algorithm for Joint Parametric Channel Estimation and Non-coherent Data Detection in an OFDM-CDMA Wireless System with Antenna Arrays
A blind joint parametric channel estimation and noncoherent data detection algorithm is proposed for the downlink of an orthogonal-frequency-division-multiplexing code-division-multiple-access (OFDM-CDMA) system with multiple-input-multiple-output (MIMO) antenna arrays. To reduce the computational complexity, we first develop a tree-structured algorithm to estimate high dimensional parameters p...
متن کاملOn the Performance of Different Channel Pre-Compensation Techniques for Uplink Time Division Duplex MC-CDMA
Time division duplex multi-carrier code-division multiple-access (TDD/MC-CDMA) operates on the premise that there is a strong correlation between upand downlink channel conditions. When using TDD mode, the effects of the channel on the uplink signal can be pre-compensated at the mobile station, based on the channel estimation from the downlink frame. The aim of this paper is to carry out a perf...
