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. homes for sale in austinburg ohioWebOFDM 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]. homes for sale in austin minn
