Abstract
Carrier and symbol recovery in severely faded Nakagami-m channel is a challenging area. It requires design of certain systems that can capture the carrier and symbols during the reception process. There are several known approaches [1–3] but very few report the use of Phase-Locked Loop (PLL)-based methods [4–7]. Here, in this chapter, we propose a Digital Phase-Locked Loop (DPLL)-based system for carrier and symbol recovery in severely faded Nakagami-m channel. We report the performance of the proposed system in terms of Symbol Error Probability (SEP) while recovering carrier and symbols from QPSK-modulated signals in presence of phase error. SEP performance of the DPLL is compared for cases of uncoded and BCH (15, 7) coded conditions. Results shows that the SEP performance improves significantly on application of BCH (15, 7)-based error detection and correction mechanism when used with the DPLL-based system.
