Comparison of DPCM and Subband Codec performance in the presence of burst errors

Creator:

Bhutani, Meeta

Abstract:

This thesis is a preliminary study of the relative performance of the major speech compression techniques, Differential Pulse Code Modulation (DPCM) and Subband Coding (SBC) in the presence of transmission distortion. The combined effect of the channel distortions and the channel codec including error correction is represented by bursts of...

A simple RLS-POCS solution for reduced complexity ADSL impulse shortening

Creator:

Helms, Sheldon J.

Abstract:

Recently, with the realization of the World Wide Web, the tremendous need for high-speed data communications has grown. Several access techniques have been proposed which utilize the existing copper twisted pair cabling. Of these, the xDSL family, particularly ADSL and VDSL, have shown great promise in providing broadband or near-broadband...

Interactive Internet connection for a remote digital signal processing lab

Creator:

Ehler, Michael

Abstract:

A remote Digital Signal Processing (DSP) lab for the Internet is developed to give students the opportunity to work together online with a remotely located Digital Signal Processor (DSP). Students in different locations can work together with the DSP as if they were present in the lab. To make this...

Complexity and performance analysis of turbo decoders for wireless communication systems

Creator:

Rangarajulu, Suresh

Abstract:

The quest to achieve reliable communication has always existed. Error Correcting codes have made communication systems even more reliable under high signal to noise ratios. A new class of codes called Turbo codes have proved to be more effective compared to the other classes of codes and achieve performance close...
