Collision study for the one-way IVDS channel

Abstract

dc:description.abstract

A collision study is performed to compare the interference rejection characteristics of two spread spectrum receivers, one employing a sliding correlator and the other using a more sophisticated matched filter design. The testing involves using two similar transmitters, one acting a the jammer, to test the collision dynamics of each receiver. Packet data from both transmitters contain identical spreading codes. Data from the testing is analyzed and the receivers' jamming margin, capture, and process gain qualities are compared as to which system best optimizes a one-way channel. Motivation for the collision study stems from researching a one-way communication link for the Interactive Video Data Service ( IVDS ) project currently being developed by the Center for Wireless Telecommunications ( CWT ) at Virginia Tech. A novel retransmission technique has previously been developed which discusses the probability of packet collisions on the channel and uses a computer program to simulate the channel model. This thesis will provide more information as to what happens in packet collisions as well as determine which receiver type offers the greatest interference rejection.
