Abstract :
The application of Bonferroni-type bounds is investigated for orthogonal space-time block codes over a keyhole Nakagami-m fading channel, which includes a cascaded Rayleigh fading channel as a special case. In particular, upper and lower bounds on the symbol error rate and bit error rate are derived and shown to be very tight at any signal-to-noise ratio. The developed bounds are applicable for arbitrary signal constellations and mappings and can be accurately computed with single finite-range integrals.
