Performance analysis on coded system over quasi-static (MIMO) fading channels

In this paper, we derive closed-form upper bounds on the error probability of coded modulation schemes used for multi-input multi-output (MIMO) quasi-static fading channels. The bounds are obtained from new tight union-bound techniques, and can be readily calculated when the distance spectrum is given. In deriving the bounds for the MIMO system, we assume the use of orthogonal space-time block code (OSTBC) as the inner code. The outer code is the block code. We obtain an equivalent single-input single-output (SISO) channel model for this concatenated coded-modulation system. The upper bounds derived here indicate good match with the simulation results of the complete transceiver the system in which the turbo-iterative decoding algorithm is employed at the receiver.
