A Serial Unequal Error Protection Codes System Using MMSE-FDE for Fading Channels

Abstract: In our previous research, to achieve unequal error protection (UEP), we proposed a scheme which encodes the data by randomly switching between several codes which use different signal constellations and showed the effectiveness in AWGN channels. In this paper, we propose our UEP system using MMSE-FDE (frequencydomain equalization based on the minimum mean square error criterion) for fast and selective fading by using the fact that importance levels are changed every few symbols, i.e., every block, in the propo… Show more

“…In previous research, we proposed 8‐ASK‐type, RING‐type, and trapezoid‐type signal constellations, and the effectiveness of the proposed UEP system for additive white Gaussian noise (AWGN) channels was shown 22. Next, we proposed a finite impulse response (FIR) linear equalizer based on the normalized least mean square (LMS) algorithm 23,24 and a decision feedback equalizer (DFE) based on the recursive least squares (RLS) algorithm 25 as a frequency selective fading measure. As a result, we showed the effectiveness of the proposed UEP system.…”
