Abstract :
The authors have proposed a method of very efficient wireless frequency usage. It is based on the measurement of the multipath property for each time slot and the coherent addition of multipath signals. The method has been implemented an LSI chip. This paper applies a new signal design method on the coherent addition of multipath signals.
