Abstract
We study the information outage probability (IOP) and constrained capacity of moderate-length codes over AWGN channels based on M-ary phase-shift keying signals. The IOP provides an important benchmark for performance evaluation of moderate-length codes. We analytically compute the IOP and compare

From the information theoretic measure, channel capacity provides a fundamental understanding of the performance on a signaling type over a channel
We study the performance of Protected Tactical Waveform (PTW) [17, 18], which employs M-PSK signals, using Second Generation Digital Video Broadcasting Satellite (DVB-S2) forward error correcting (FEC) code with numerous code rates, and a fixed length of 16, 200 coded bits
Computer simulations for Quadrature Phase Shift Keying (QPSK) and 8-Phase Shift Keying (8-PSK), using DVB-S2 FEC with a fixed length of 16, 200 coded bits, code rates Rc of 1/4, 1/3, 1/2, 2/3, 3/4 and 8/9 are considered
Summary
From the information theoretic measure, channel capacity provides a fundamental understanding of the performance on a signaling type over a channel. The IOP results obtained by previous studies [11, 16] are satisfactory only for the codes which operate in the region of low to moderate SNR where the maximum capacity or Shannon capacity matches the constrained capacity. These results rely on Gaussian distribution assumption of the input signal. Codeword error rate and block error rate are used interchangeably
