In this paper, exact statistics for the linear combination of gamma conditionally Gaussian random variables (CGRVs) are obtained. In particular, the probability density function (PDF), the cumulative distribution function (CDF) and the moment generating function (MGF) are derived. Closed form expressions are obtained for both integer and noninteger parameters, using the Mellin-Barnes integral representation...
Cooperation in a cellular network is seen as a key technique in managing other cell interference to observe a gain in achievable rate. In this paper, we present the achievable rates for a cloud radio network using a zero forcing (ZF) equalizer with dirty paper precoding (DPC). We show that when complete channel state information is available at the cloud, rates close to those achievable with total...
In this paper, bit error rate (BER) expressions for the λ-MRC receiver for a decode and forward (DF) cooperative system are obtained for Nakagami-m fading, where m is not an integer. Previous results were available only for integer values of m. BER analysis is done by employing approximate statistics of a gamma conditionally gaussian (CG) random variable (RV) obtained through the Loskot-Prony approximation...
Exact expressions are obtained for the bit error rate (BER) for coherent and noncoherent decode and forward (DF) cooperative systems with two relays. The piecewise linear (PL) combiner, a close approximation to the maximum likelihood (ML) detector, is employed at the receiver. BER analysis is done using a contour integral approach for evaluating the Gil-Pelaez integral involving the characteristic...
In this paper, we provide exact expressions for the bit error rate (BER) for single relay maximal ratio combining (MRC) based decode and forward (DF) cooperative systems in Nakagami-m fading. This is done by expressing the decision variable as a sum of gamma conditionally Gaussian (CG) random variables. The characteristic function (CF) of gamma CG variables is then derived and used to obtain the BER...
