In this paper, we investigate multihop communication systems with regenerative relays over Nakagami fading channels and propose a simple approach for performance evaluation. Relaying terminals and destination terminal are assumed to adopt coherent detection. Based on the characteristic of M-ary Phase-Shift Keying (MPSK) constellation modulation signals, symbol error rate (SER) expressions are derived...
In this paper, we consider the performance of orthogonal space-time block codes (OSTBCs) over Weibull fading channels. Based on the equivalent single input single output (SISO) model, we first present the probability density function (PDF) of the instantaneous single to noise ratio (SNR) per symbol, and then derive a close-form expression for the outage probability of OSTBCs. We also evaluate the...
Space-time block coding is a modulation scheme recently discovered for the transmit antenna diversity to combat effects in wireless fading channels. In this paper, using the equivalent single-input single-out (SISO) model, we present closed-form expressions for the exact symbol error rate (SER) and bit error rate (BER) of orthogonal space-time block codes (OSTBCs) with M-PSK and M-QAM modulations...
Space-time block coding is a modulation scheme recently discovered for the transmit antenna diversity to combat effects in wireless fading channels. In this paper, using Meijer's G function, we give the closed-form capacity expressions of orthogonal space-time block codes (OSTBCs) over usual uncorrelated fading channel (Nakagami-m, Ricean) and correlated Rayleigh fading channel. The closed-form capacity...
