Frequency-Domain Equalization (FDE) based on Minimum Mean Square Error (MMSE) criterion is a powerful equalization technique for the broadband Single-Carrier (SC) transmission. However, the presence of timing offset produces the Inter-Symbol Interference (ISI) and degrades the Bit Error Rate (BER) performance. As the roll-off factor of the transmit filter increases, the performance degrades more. Recently, the authors proposed joint MMSE-FDE & spectrum combining which can achieve the frequency diversity gain while suppressing the negative impact of timing offset for the SC transmission. In this paper, they extend the joint MMSE-FDE & spectrum combining to include the antenna diversity reception.
