With the advent of the 4G broadband wireless communications, the combination of multiple-input multiple-output (MIMO) wireless technology with orthogonal frequency division multiplexing (OFDM) has been recognized as one of the most promising techniques. In particular, coding over space, time and frequency domains provided by MIMO-OFDM enables a much more reliable detection and decoding of the message...
Most, if not all, of the complexity reduction algorithms for turbo product code are concentrated only on the decoding part in previous literatures. In this paper, we propose very low complexity decoding algorithm for turbo product codes by considering both the encoding and decoding aspects. For the encoding part, a new encoding scheme is presented for turbo product codes to reduce the computing complexity...
Tomlinson-Harashima precoding (THP) can be combined with geometric mean decomposition (GMD) to decouple a multiple input multiple output (MIMO) channel into multiple subchannels with identical signal-to-noise ratio (SNR). The combined system is called GMD-THP MIMO system. As the subchannels have identical SNR, it is more convenient for GMD-THP MIMO systems to design modulation/demodulation and coding/decoding...
