Abstract
An arrangement for acquiring an input signal has a complex multiplier (30) which receives two staggered channels (42I and 42Q). The first channel is delayed (31). A phase error estimator (22) then estimates the error in each of the channels. Another delay (23) re-introduces the delay between the two channels. Another complex multiplier (24) produces the output (34I and 34Q) which is fed-back to complex multiplier (30).
