Space–Time/Space–Frequency/Space–Time–Frequency Block Coded MIMO-OFDM System with Equalizers in Quasi Static Mobile Radio Channels Using Higher Tap Order

QOSTBC coded MIMO system with reduced complexity and optimised decoding for rank deficient channels

“…Multiple‐input multiple‐output (MIMO) wireless communication systems [1, 2] are known for capacity gains, higher spectral efficiency and better fading mitigation. To increase the transmission rate with a reduced bit error rate (BER) in MIMO systems, orthogonal space‐time block codes (OSTBCs) [3–9] are employed. In such systems the maximum likelihood (ML) detection is most common for MIMO symbol detection.…”

Moment generating function‐based pairwise error probability analysis of concatenated low density parity check codes with Alamouti coded multiple input multiple output‐orthogonal frequency division multiplexing systems

“…These papers neither considered any concatenation scheme nor the presence of OFDM for BER performance improvement. Papers [17][18][19][20] derive exact BER expressions for OSTBC codes in generalised Rayleigh and Rician fading channels in MIMO correlation channels, but no concatenation with channel coding techniques and OFDM is considered. In [21], the moment generating function (MGF) approach is used to analyse the PEP performance bounds for various channel coding techniques like convolutional codes, trellis codes etc.…”

Tensor space/time coding for MIMO wireless communication systems

“…The combination of ST, SF or STF codes and multiplexing access techniques in the MIMO systems has received much attention in the last years. In the MIMO-OFDM system, SF and STF codings have been employed for providing high data rates and/or reliability through the system diversities available [25,28,32,34,35,36,37,38,39]. For the same purpose, the MIMO-CDMA and MIMO-SDMA systems have exploited the ST diversities [40,41,42,17,43,12,44].…”
