Random Network Coding Effects on CDMA/TDD Mesh Networks

Abstract

The effects of random network coding on code division multiple access/time division duplex (CDMA/TDD) platforms are studied and evaluated. A multi-hop mesh network with both single source and multiple receiving nodes is assumed. Two scenarios are evaluated for their efficiency. The study focuses on the effects of uncontrolled parameters such as the minimum number of neighbors and the network connectivity, and of controlled parameters such as the Galois Field (GF) size and the Processing Gain. The results show that applying random network coding to code division multiple access/time division duplex systems could provide a noticeable improvement in overall efficiency.
