METHOD AND SYSTEM FOR DETECTING CODE SEQUENCES IN ULTRA-WIDEBAND SYSTEMS

摘要

A method and a system are provided for detecting a code sequence in an ultra- wideband system. An on-off keying (OOK) detector is used for detecting a code sequence. A soft despreader is used for despreading the energy of the code sequence to provide a plurality of multipath energies. A RAKE combiner combines the plurality of multipath energies obtained from the soft despreader. The soft despreader and the RAKE combiner enable operation of an OOK receiver without using a timing recovery process block.
