Segmented architecture for multiple sequence detection and identification in fading channels |
August 3, 2004 |
| 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. |
