In this work, we propose a new approach to design a STBC recognizer for OFDM transmissions by taking benefits from the a posteriori probabilities provided by a channel decoder. The mathematical treatments have shown that the exact maximum-likelihood (ML) solution to this problem is computationally demanding in the absence of a closed form. WebOFDM is known to combat ISI very effectively, and therefore can simplify the code design problem for frequency selective channels. It was shown in [9] that BICM with OFDM can achieve the maximum frequency diversity. Using multiple antennas and by applying STBC to BICM OFDM systems, one can achieve the maximum diversity in frequency and space [10]. flight checker cheap flightsWebcoding (STBC) is fundamental to providing space diversity by supplying multiple independently faded replicas of the same information symbol, increasing communication reliability [2]. However, efﬁcient channel estimation is still a challenging issue when increasing either the number of antennas or subcarriers in MIMO-OFDM (orthogonal … flight checker birmingham
