Space-time modulated codes for memory channels: capacity and information rates, zero-forcing decision feedback equalizer

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 I/sub i.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
