Abstract

Information rates of multiple-input multiple-output (MIMO) systems over frequency-selective fading channels are computed under the constraint of independent identically distributed inputs chosen from a finite alphabet. The method uses a simulation based approach that employs the sum-product algorithm. The setting includes as special cases the single-input single-output systems over frequency-selective fading channels and the MIMO systems over flat fading channels. Both ergodic and nonergodic channels are considered, and examples are provided for the case of binary signaling.
