Combined Channel Estimation with Interference Suppression in CPSS

Joint Channel-data Estimation with Interference Suppression

This paper describes an adaptive space-time receiver with joint channel and data estimation (JCD) to combat time-varying multipath channels in the presence of undesired co-channel interference (CCI). The receiver uses a colored Gaussian metric in the sequence detection to suppress the CCI. The proposed scheme also uses the knowledge of the transmit filter for improved channel estimation to enha...

An interference suppression scheme with joint channel-data estimation

Gaussian Z Channel with Intersymbol Interference

In this paper, we derive a capacity inner bound for a synchronous Gaussian Z channel with intersymbol interference (ISI) under input power constraints. This is done by converting the original channel model into an n-block memoryless circular Gaussian Z channel (n-CGZC) and successively decomposing the n-block memoryless channel into a series of independent parallel channels in the frequency dom...

Performance of coded DS-CDMA with pilot-assisted channel estimation and linear interference suppression

We consider a direct sequence (DS-) code division multiple access (CDMA) system with orthogonally multiplexed pilot signals and minimum mean squared error (MMSE) data and channel estimation. Both flat and frequency-selective fading channels are considered. Large system analysis is used to optimize the pilot-to-data power ratio (PDR) and the code rate for a fixed bandwidth expansion. Specificall...
