Duong Hyundong Shin and Een-Kee Hong School of Electronics and Information Kyung Hee University 1 Seocheon-dong Giheung-gu Yongin-si Gyeonggi-do 446-701 South Korea Received 21 June 2007 Accepted 30 October 2007 Recommended by Ibrahim Develi We analyze the exact average symbol error probability SEP of binary and M-ary signals with spatial diversity in Nakagami-q Hoyt fading channels. The maximal-ratio combining and orthogonal space-time block coding are considered as diversity techniques for single-input multiple-output and multiple-input multiple-output systems respectively. We obtain the average SEP in terms of the Lauricella multivariate hypergeometric function Fp . The analysis is verified by comparing with Monte Carlo simulations and we further show that our general SEP expressions particularize to the previously known results for Rayleigh q 1 and single-input single-output SISO Nakagami-q cases.

INTRODUCTION In digital communications the accurate calculation of average symbol error probability SEP for a variety of modulation schemes has been an area of long-time interest see 1-12 and references therein . A unified method for deriving the error probability over fading channels has been presented by using alternative representation of the Gaussian and Marcum Q-function 1 2 . By their alternative representations the average error probability can be expressed in the form of a single finite-range integral whose integrand contains the moment .
