Analysis of Second-order Statistics Based Semi-blind Channel Estimation in CDMA Channels
نویسندگان
چکیده
| The performance of second order statistics (SOS) based semi-blind channel estimation in long-code DS-CDMA systems is analyzed. The covariance matrix of SOS estimates is obtained in the large system limit, and is used to analyze the largesample performance of two SOS based semi-blind channel estimation algorithms. A notion of blind estimation e ciency is also de ned and is examined via simulation results.

Blind equalization of multiuser CDMA channels: a frequency-domain approach
The blind estimation of mixing channels resulting from frequency selective fading and multipath in a multiuser CDMA system is an important problem in wireless communications. We present a novel frequency-domain approach using second order spectral statistics for recovering the unknown channels. Unlike other methods which are based on time-domain analysis we make no particular assumption about t...
متن کاملBlind and Semi-blind Single User Receiver Techniques for Asynchronous Cdma in Multipath Channels
We consider multiple users in an asynchronous DS-CDMA system operating in a multipath environment. The received cyclostionary spread signal sampled at the chip rate is converted to a stationary vector signal, leading to a linear multichannel model. Linear receivers for multiple access interference (MAI) suppression are studied with emphasis on computationally simple algorithms. The desired user...

متن کاملBlind ICA detection based on second-order cone programming for MC-CDMA systems
The multicarrier code division multiple access (MC-CDMA) technique has received considerable interest for its potential application to future wireless communication systems due to its high data rate. A common problem regarding the blind multiuser detectors used in MC-CDMA systems is that they are extremely sensitive to the complex channel environment. Besides, the perturbation of colored noise ...
متن کاملPerformance 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...
