Abstract— In wireless sensor networks (WSNs), reducing energy consumption of resource constrained sensor nodes is one of the most important issues. In this paper, we propose a ta...
--- In this paper, a novel third-order Phase Lock Loop (PLL) is proposed for the timing recovery in MIMO-OFDM systems. It differentiates from conventional timing recovery algorithm...
Abstract— The performance analysis of a system employing coordinate interleaving and constellation rotation, over Nakagamim fading channels, in the presence of phase noise as wel...
— In this paper we discuss the effect of phase noise at both, transmitter and receiver in an OFDM system. We study an iterative equalization system at the receiver. The system is...
This paper addresses initial ranging (uplink synchronization and power control) for TDD OFDMA systems. Exploiting the channel knowledge from the downlink channel together with ini...
