WIRELESS COMMUNICATION TRANSMITTER AND RECEIVER

摘要

A wireless communication transmitter comprises a part (1) for coding an information signal, a part (7) for holding a preamble signal consisting of a known signal sequence, and a part (5) for attaching the preamble signal to the coded information signal. The preamble signal has at least in part a cycle of Tw/N determined depending on the type of communication system used for transmission, where Tw is symbol length and N is a positive integer.
