A method for frequency domain to time domain conversion includes receiving a set of frequency-domain samples. Based on the set of frequency-domain samples, a first sample subset comprising a predetermined fraction of the number of samples of the set of frequency-domain samples and a second sample subset comprising the predetermined fraction of the number of samples of the set of frequency-domain samples are generated. A linear phase rotation is applied to the first sample subset and the second sample subset to produce a phase rotated first sample subset and a phase rotated second sample subset. The phase rotated first sample set is post-processed to generate a first set of time-domain samples. The phase rotated second sample set is post-processed to generate a second set of time-domain samples. The first set of time-domain samples and the second set of time-domain samples are reordered to produce an output set of time-domain samples.
