This paper considers the design of linear
frequency-domain receivers with oversampling for OQPSK
(Offset Quaternary Phase Shift Keying) signals. Based on
a receiver structure able to eliminate the residual interference
between in-phase (I) and quadrature (Q) components
at the sampling instants, a method that minimizes the
overall residual ISI (Inter-Symbol Interference) plus IQI
(I-Q interference) is proposed. Therefore, this receiver significantly
outperforms previous frequency-domain OQPSK
receivers.
