On the design of coded MIMO systems
Résumé
In this paper, we investigate two approaches which deal with the construction of space-time block (STB) codes for a system possessing a forward error correcting (FEC) code at the transmitter side. The first approach designs the STB codes to be optimal for a system equipped by a turbo MMSE equalizer at the receiver side, with a minimum peak to average power ratio (PAPR) constraint. The second one proposes to design the STB codes according to a non-asymptotic design criterion based on the bitwise mutual information (BMI) maximization at a specific target SNR. Performance assessments of designed codes are validated by Monte Carlo simulations.
