Abstract

This paper introduces a STFC-LDPC (space-time- frequency code low density parity check) concatenated coding scheme for high performance MIMO (multiple input, multiple output) systems. The coding design and performance evaluation are illustrated for various frequency-selective block fading conditions and compared with a STC-LDPC (space-time code LDPC) concatenated scheme over quasi-static fading conditions. The codes were analyzed and compared in space-selective conditions using various PDPs (power-delay profiles) to illustrate the performance gain of this newly proposed coding technique. The proposed STFC-LDPC showed a performance increase compared to the STC-LDPC scheme due to the inherent higher diversity of the STFC and is a suitable coding technique for high performance MIMO systems.
