Multi-User Communication using Chaotic Frequency Modulation

In this paper we consider the use of the chaotic frequency modulation (CFM) in multi-user communications. In this scheme the base station transmits the reference signal with chaotically varying frequency. All users synchronize their chaotic oscillators to this signal and use it to generate their own information-carrying CFM signal. Using numerical simulations and experiments with electronic cir...

High-speed Wireline Communication Systems

This report is a literature survey on multicarrier wireline communication systems, focusing primarily on the recent enhancements to the physical layer in Discrete Multitone (DMT) Modulation systems. We investigate methods used to improve the data rate versus reach performance of DMT systems proposed in the G.992.3 Asymmetric Digital Subscriber Lines-2 (ADSL2) and G.992.5 ADSL2+ standards. We al...

Communication over Channels with Causal Side Information at the Transmitter

This work deals with communication over the AWGN channel with additive discrete interference, where the sequence of interference symbols is known causally at the transmitter. We use Shannon’s treatment for channels with side information at the transmitter as a framework to derive “optimal precoding” and “channel code design criterion” for the channel with known interference at the transmitter. ...

Joint Transmitter-Receiver Optimization for Bonded Wireline Communications

With the advent of DSL services, high data rates are now available over phone lines, yet higher rates are in demand. In this paper, we optimize the transmit filters that can be used over wireline channels. Results showing the bit error rates when optimized filters are used, and with a decision feedback equalizer (DFE) employed in the receiver, are given. We then show that significantly higher t...
