Outage Probability and Performance of Moderate-Length Codes under Partial-Band Noise Jamming (PBNJ)

Abstract

This paper presents a theoretical approach for estimating the performance of moderate-length codes under partial-band noise jamming (PBNJ). The approach is based on the outage probability, which is the probability that the mutual information rate random variable is less than the code rate. This paper is an extension of previous work where we obtained a closed form expression for the outage probability of moderate-length codes under additive Gaussian noise channel (AWGN) [8]. Using the results under AWGN, we obtain a closed form expression for the outage probability under partial-band noise jamming (PBNJ). Using this result, we show that a smart jammer is driven to employ a full-band (FB) noise jamming. Relative to FB jamming, there is no advantage of PBNJ. These analytical results are compared against simulation results obtained for Protected Tactical Waveform (PTW) using Second Generation Digital Video Broadcasting Satellite (DVB-S2) forward error correction (FEC) codes under PBNJ.
