Consumer communications based on spread spectrum techniques

This paper shows consumer applications of spread spectrum techniques in the following areas: power line communication, data carrier, radio remote control, ISM wireless LAN, vehicle to vehicle communication, and digital TV broadcasting. One of the most difficult problems for a spread spectrum communication system is how to synchronize the receiver to the transmitted signal. The sliding correlator method is the typical and simplest, but needs a long acquisition time for synchronisation. Matched filter and convolver methods need much shorter acquisition time and SAW devices are adapted to them
