This paper investigates the tradeoff between diversity and multiplexing of orthogonal space-time block coding (OSTBC) for correlated Nakagami-m fading. For a given transmission rate, the outage probability as function of the multiplexing gain and signal-to-noise ratio (SNR) is derived. Following the negative slope of the outage probability versus SNR curve,(More)
In this paper, the expectation-maximization (EM) algorithm for maximum a posteriori (MAP) estimation is employed to derive an iterative soft-in soft-out (SISO) detection scheme for differential unitary space-time modulation (DUSTM) system employing cyclic group codes. The data sequence produced by conventional differential detection is differentially(More)
Considering frequency-selective Nakagami-m fading multiple-input multiple-output (MIMO) channels in the presence of spatial correlation, we study the error probability of orthogonal space-time block-coded (OSTBC) orthogonal frequency-division multiplexing (OFDM) systems. Exploiting the equivalent single-input single-output (SISO) OFDM model, we derive an(More)
We investigate the optimum combing system of a Rician fading signal with unequal power Rician interferers and thermal noise. Based on the statistical characteristics analysis of the output SINR, we derive a close form upper bound for the symbol error probability of M-ary phase-shift keying. Simulation results demonstrate the tightness of the derived bound.
In this paper, we address the problem of joint angle and frequency estimation based on uniform linear array (ULA). We derive a new version of ESPRIT-type algorithm to solve this problem. The proposed method follows the classic data stacking and real processing techniques for signal subspace estimation. We transform the estimated real signal subspace back to(More)
