1. Introduction This paper presents a new methodology for realizing a Rice channel in BAN Over-The-Air (OTA) testing using a fading emulator with a dynamic phantom. For the proposed apparatus to be effectual, the fading emulator must be provided with an appropriate K-factor that represents the actual propagation environment indoors. Further, an implementation of the Rice channel to the proposed...

Network clustering has been proposed as an efficient approach for addressing the problems arising from the continually increasing network density. Beside the congestion relieving and the coverage extension, cluster-based networks provide considerable energy savings, improving the sustainability of low-power networks. It has been shown that the energy efficiency and the network reliability are f...

OFDM renders multipath channels with nite memory equivalent to parallel at fading subchannels, over which equalization amounts to simple phase compensation. If the channel status information is known at the transmitter side, optimal power loading across subchannels is possible. Users mobility, time and carrier asynchronism introduce variations in the equivalent channel impulse response setting ...

The performance of the minimum mean-squared error (MMSE) receiver for detection of direct sequence code division multiple access is considered in various fading channel models. Several modifications to the basic MMSE receiver structure which have been recently proposed for use on nonselective fading channels are reviewed and shown to represent different approximations to a single common form. T...

In this letter, the performance of turbo codes is evaluated through analysis and simulation over the Rice multiplicative fading channel. The analysis is conducted extending the results presented by Viterbi and Viterbi (1998) to the Rice multiplicative fading channel case. Simulation results are obtained using an extended version of the improved Jakes’ channel simulator, first presented by Pop a...

Secret sharing over the fast-fading MIMO wiretap channel is considered. A source and a destination try to share secret information over a fast-fading MIMO channel in the presence of a wiretapper who also makes channel observations that are different from but correlated to those made by the destination. An interactive authenticated unrestricted public channel is also available for use by the sou...

We investigate the effects of both fading correlations and transmitter channel knowledge in multiple element antenna (MEA) communication systems. While for independent and identically distributed, fades between receive and transmit antennas, pioneering work showed that a huge increase in capacity is possible for MEAs compared to a single antenna system, recent contributions warn that fading cor...

In this paper, the capacity and error probability of orthogonal space-time block codes (STBCs) are presented for PAM/PSK/QAM modulation in correlated flat fading channels. We consider an equivalent scalar AWGN (additive white Gaussian noise) channel with a channel gain proportional to the Frobenius norm of the matrix channel. A unified approach to the error probability analysis for correlated R...

This paper addresses the problem of energy detection of an unknown deterministic signal over a general fading channel model. More particularly, a closed-form mathematical expression is derived for the energy detector's probability of detection over a-# generalized fading channel with selection combining diversity reception. The derived expression can be used to study the performance of energy d...

We consider the problem of the optimal route selection in the presence of Rician fading channel. The variation in the signal strength due to fading is an overlooked fact in the wireless sensor networks. The conventional route selection strategies neglect the effect of fading and provide the low throughput routes for the data transmission. We consider the underlying dynamics of the wireless comm...
