Zero-delay Channel Estimation Based on Pilot and Traffic Channels for Ds/cdma Systems
نویسندگان
چکیده
Abstract In this paper, a zero-delay channel estimation scheme based on both pilot and traffic channels is proposed for next generation direct sequence codedivision multiple-access (DS/CDMA) systems. This scheme has no channel estimation delay, and is found to perform significantly better than a zero-delay channel estimation scheme based on only pilot channel. The elimination of channel estimation delay reduces system delay error including power control error. The performance of the proposed scheme is insensitive to combining coefficients.

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 کاملPilot Aided Channel Estimation for Short-Code DS-CDMA
This paper investigates pilot based channel estimation techniques for short code DS-CDMA in a multipath environment. It will be shown that the conventional correlative estimation algorithm is biased and very sensitive to multi-user interference (MUI). Therefore, we suggest two advanced estimation algorithms. The first one eliminates the inherent path cross talk and yields an unbiased estimate w...
متن کاملDesign of Channel Estimation Filters for Pilot Channel Based DS-CDMA Systems
The accuracy of channel estimation significantly affects the performance of coherent receiver in a DS-CDMA system. The receiver performance can be improved if an appropriate channel estimation filter is used according to the channel condition. In this paper, we consider the design of channel estimation filters for pilot channel based DS-CDMA systems. When a moving average (MA) FIR filter is use...
