This paper investigates the performance of orthogonal space-time block codes over generalized- K fading multiple-input-multiple-output (MIMO) channels. We present exact analytical expressions for three important performance measures, namely, outage probability, average capacity, and average symbol error rate (SER). In addition, we derive simple expressions for key parameters dictating the system performance at the high and low signal-to-noise ratio (SNR) regimes, i.e., diversity order, coding gain, minimum energy per information bit, and wideband slope, which provide insight on how various key system parameters, such as number of antennas and fading severity level, affect the performance of the system.
