Image of FIG. 1.
FIG. 1.

Illustration of the SER versus average received SNR (at relay) ; comparison of analysis and simulations. Each set of curves represents a specific antenna configuration of the form ( , , ). For configurations with = 2, the full-rate Alamouti OSTBC is used (i.e., = 1), while for = 4, a rate 1/2 orthogonal design is employed (i.e., = 1/2). In all cases, QPSK digital modulation is assumed, such that = 4. The relay power is assumed to scale with by setting .

FIG. 2.

Illustration of the mean κ, variance κ, and third cumulant κ of the received SNR at the destination γ, as a function of the average received SNR at the relay . In each case, the simulated cumulants are compared with those obtained based on the Coulomb fluid approximation. As in Fig. 1 , each set of curves represents a specific antenna configuration of the form ( , , ). For configurations with = 2, the full-rate Alamouti OSTBC is used (i.e., = 1), while for = 4, a rate 1/2 orthogonal design is employed (i.e., = 1/2). The relay power is assumed to scale with by setting .

FIG. 3.

Illustration of the SER versus average received SNR (at relay) ; comparison of analysis and simulations. Results are shown for = = and = 2, with the full-rate Alamouti OSTBC code (i.e., = 1). QPSK digital modulation is assumed, such that = 4. The relay power is assumed to scale with by setting .
