The authors present a novel theoretical method to analyse the maximal ratio combining (MRC) receivers using BPSK and M-PSK modulation in spatially correlated Rayleigh fading channels, with perfect and imperfect channel knowledge, in terms of antenna array configuration and parameters of scatterer distributions. In this analysis closed form expressions for error probabilities of these modulation...

Acceptable temperature is very important for mine refuge chamber (MRC) to ensure the safety of occupants. A novel control scheme combining cold source storage with compressed air (MCA) was proposed MRCs. An experiment conducted explore characteristics controlling in a MRC via MCA. Effects several main factors such as initial surrounding rock (ISRT), ventilation (VT), rate (VR) and heat (HR) on ...

OBJECTIVE To determine the prognostic value of clinical assessment and motor evoked potentials for upper limb strength and functional recovery after acute stroke, and to establish the possible use of motor evoked potentials in rehabilitation. DESIGN A prospective study. SUBJECTS Fifty-two patients with hemiparesis were enrolled one month post-stroke; 38 patients concluded the study at 12 mo...

At receiving high data rate in ultra wideband (UWB) technology for many users, there are multiple user interference and inter-symbol interference as obstacles in the multi-path reception technique. Since the rake receivers were designed to collect many resolvable paths, even more than hundred of paths. Rake receiver implementation structures have been proposed towards increasing the complexity ...

Evans DH. Teleost fish osmoregulation: what have we learned since August Krogh, Homer Smith, and Ancel Keys. Am J Physiol Regul Integr Comp Physiol 295: R704– R713, 2008. First published June 4, 2008; doi:10.1152/ajpregu.90337.2008.—In the 1930s, August Krogh, Homer Smith, and Ancel Keys knew that teleost fishes were hyperosmotic to fresh water and hyposmotic to seawater, and, therefore, they w...

In this study, bit error rate (BER) performance of multiple input multiple output (MIMO) systems employing transmit antenna selection with maximal ratio combining (TAS/MRC) and orthogonal space time block codes (OSTBC) is analysed and compared. Analysis has been done for several modulation schemes in equicorrelated Rayleigh fading channels. Novel infinite series expressions for BER of TAS/MRC a...

This paper derives analytically some simple closed form expressions for the average symbol error rate (SER) of M-ary phase shift keying (MPSK), M-ary differential phase shift keying (MDPSK) and noncoherent Mary frequency shift keying (MFSK) over a Nakagami-m fading channel with Lfold maximal ratio combining (MRC) and selection combining (SC) space diversity receptions. Numerical results demonst...

Han’s maximum rank correlation (MRC) estimator is shown to be √ n-consistent and asymptotically normal. The proof rests on a general method for determining the asymptotic distribution of a maximization estimator, a simple U-statistic decomposition, and a uniform bound for degenerate U-processes. A consistent estimator of the asymptotic covariance matrix is provided, along with a result giving t...

This paper investigates the bene ts of link adaptation according to the propagation conditions using multi-rate vocoders and channel coders. A multi-rate source and channel coding (MRC) system trades-o the source codec bit rate against channel codec bit rate according to the prevailing channel conditions. MRC systems continuously recon gure transmission resources to optimally combat channel deg...
