Abstract

Modulated codes (MC) are error correction codes (ECC) defined on the complex field. In this paper, we study space-time MC for memory channels. Similar to MC for single antenna systems, the space-time MC can also be naturally combined with a multiple antenna system with ISI. We derive some lower bounds on the capacities C and the information rates Ii.i.d. of the MC coded systems. As a property of space-time MC, it is shown that, for an N transmit and N receive antenna channel with memory and AWGN, there exist MC with arbitrary rates r, 0<r<1, such that the MC coded systems have larger information rates Ii.i.d. than the original system does at relatively low channel SNR. In this paper, we also propose an MC coded zero-forcing decision feedback equalizer (ZF-DFE).
