...For channels with large delay spread, FDE is computationally simpler than the corresponding time-domain equalization [22]....
[...]
...It is known that with cyclic prefix, the cyclic-shifted version of the transmitted symbol caused by the multipath can be equalized and recovered by FDE because the shift in the time domain can be recovered by a phase rotation in the frequency domain [22]....
[...]
...FDE is used for further processing due to its lower complexity over conventional time-domain equalization [11], [22]....

...In [2] the computational complexities of time and frequency domain equalizers are compared and it is shown that FDE is simpler when the length of the stationary channel impulse response exceeds the sample time by a factor of 5 or more....
