A direct- conversion receiver (DCR)reduces the power consumption and cost. However, DCR in Or-thogonal frequency division multiplex (OFDM)systems suffer from IQ imbalance. Until this time, many algorithms are proposed to compensate IQ imbalance in...
STBC is a technique to achieve transmit diversity. QO-STBC is full rate STBC constructed from relaxing orthogonality, and requires a decoder to search symbol pairs with ML decoding. Motivated by this, we have proposed single symbol decodable QO-ST...
