Employing multiple channels to improve the multi-hop wireless network performance has recently attracted a lot of attention. Given that hidden node collision is a key cause of the performance degradation in multi-hop wireless networks, we propose a s

This paper presents an adaptive combined correction and compensation (ACCC) scheme to mitigate the distortion caused by I/Q imbalance and multipath channel, for OFDM receivers. For the proposed scheme, the estimation of the I/Q and channel parameters

Multi-hop wireless sensor networks (WSN) have many applications in nowadays' environment monitoring. However, it is very challenging to predict the throughput for an arbitrary multi-hop wireless sensor network with different source data rates. In thi

This paper presents an adaptive scheme in overcoming signal distortion, caused by I/Q imbalance and multipath propagation, in an OFDM receiver. Estimation of I/Q imbalance and channel parameters is performed in the frequency domain with the aid of pi

The presence of in-phase/quadrature (I/Q) imbalance in a dual branch receiver gives rise to signal distortion. If the incoming signal is also corrupted by multipath fading, then the task of correcting or compensating for these two forms of distortion

An improvement of Signal-to-Interference Ratio (SIR) at the base station of a wireless communication system can be obtained using a suitable choice of an array antenna. In this paper we consider Concentric Circular Antenna Array (CCAA) which can be u

It is well known that dual-branch receivers suffer from in-phase (I) and quadrature (Q) imbalance problems resulting in distortion and poor signal quality. This paper presents a novel technique, incorporating adaptive estimation and compensation, to
