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...
In this paper, we propose a downlink multi-antenna multi-carrier direct-sequence code division multiple access (MC-DS-CDMA) transmission scheme, incorporating space-time-frequency block (STFB) codes. The proposed scheme achieves time, frequency and spatial diversity using non-redundant algebraic constellation precoders. We simulate the proposed system's bit-error-rate (BER) performance in a statistically...
This paper introduces a realistic MIMO platform which was created according to the IEEE 802.16e-2005 standard (WiMAX). The MIMO-WiMAX platform is computationally efficient and capable of simulating space-selective, time-selective and frequency selective fading conditions. The simulator can simulate any arbitrary power-delay profile without increasing the receivers sampling frequency. The simulator...
