A filter co-processor comprising:
a first memory (103) for storing data information;
a second memory (106) for storing coefficients; and
a controller (109) for controlling a multiplier/accumulator to perform multiply/accumulate
functions during a correlation process between the stored data information representing a
complex data sequence and the stored coefficients representing a mid-amble sequence, where the
mid-amble sequence comprises alternating pure real/pure imaginary complex values and the output
of the correlation is decimated, the controller coordinating retrieval of the stored data information
and the stored coefficients.
