In this paper, we show that the direct transmission scheme of low-density parity-check (LDPC) codes can achieve the upper bound of rate-diversity tradeoff with probability one for multiple-input multiple-output (MIMO) systems with BPSK modulation. We then present an algorithm to construct the LDPC space-time codes through a 2-dimensional array whose doubly-periodic correlation is bounded by 1.
