Concatenated space-time codes for quasi-static fading channels: Constrained capacity and code design Conference Paper uri icon

abstract

  • The problem of designing codes with close-to-capacity performance on the multiple-input multiple-output (MIMO) quasi-static fading channel (QSFC) is addressed. We consider three different coding schemes - namely, direct transmission of random-like codes, concatenation with linear processing orthogonal space-time block codes (o-STBC) and concatenation with space-time trellis codes (STTC). The constrained modulation outage capacity of each of these schemes is computed. It is shown how Low-density Parity Check (LDPC) codes may be used to approach capacity in these cases. For the STTC, the serial concatenation scheme of [1] turns out to have close to capacity performance.
