Known sequences are detected and identified in a fast fading environment
using a segmented correlator and FHT (Fast Hadamard Transform)
architecture. The incoming sequence of samples or data is segmented into
blocks. Each block is individually detected using a correlator/FHT
segment. Each sequence identifying output of each correlator/FHT segment
is summed with the corresponding output of other correlator/FHT segments.
Each sum is compared with a threshold to determine whether a particular
sequence has been detected and identified.
