  • Introduction

The Digital Communications Laboratory is involved in various fields of signal processing and detectors. The laboratory is also active in noise modeling and development of detectors. The following is a brief description of active research projects at DCL:

·        Estimation of blind time delay for single sensors in multi-path environment.

·        Generalized autoregressive conditional heteroscedasticity.

·        Auxiliary particle altering for wireless multi-path fading channels in presence of additive ARCH.

·        Development of blurred image restoration method using hidden Markov modelling and minimum entropy approach.

·        Development of WCDMA detectors based on CA/OS CFAR.

·        Development of methods for detecting signals in k-distributed clutter.

·        Development of perturbation blind channel and signal estimation.

·        Design and development of encryption systems based on a public key.
