Abstract
This paper studies the optimal transmission of scalable multimedia sources over multiple-input multiple-output channels. First, we derive the outage probability of a space-time code for an arbitrary piecewise-linear diversity-multiplexing tradeoff function. We next prove that, as long as a crossover point of the outage probabilities of two space-time codes exists, then as the spectral efficiency increases, the crossover point in signal-to-noise ratio monotonically increases, whereas that in outage probability monotonically decreases. Lastly, based on that, we derive a method for optimal space-time coding of a scalable multimedia sequence that contains multiple packets. It is shown that, with the proposed method, the computational complexity involved with optimal space-time coding is exponentially reduced without losing any performance. © 2015 IEEE.
