Abstract
An example technique may include controlling receiving a first block of time domain symbols and a second block of time domain symbols, converting the blocks of time domain symbols to the frequency domain to create a first pre-equalized block of frequency domain symbols and a second pre-equalized block of frequency domain symbols, respectively, applying, a linear phase shift to the frequency domain symbols to compensate for a conjugating and time-reversing of corresponding pre-spread domain symbols being performed at a transmitter before spreading of the pre-spread domain symbols, and creating a first equalized block of frequency domain symbols and a second equalized block of frequency domain symbols as a function of the first and second pre-equalized blocks of frequency domain symbols wherein at least one of the first and second pre-equalized blocks of frequency domain symbols has the linear phase shift applied.
