Title:
TRANSMITTER, RECEIVER, AND MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2006/109539
Kind Code:
A1
Abstract:
A transmitter comprises a spread code multiplying means for multiplying a symbol indicative of a reference signal by a spread code to generate a spread chip sequence; a chip pattern generating means for subjecting the spread chip sequence to a predetermined number of chip repetitions to generate a predetermined chip pattern; and a multiplying means for multiplying a signal having the chip pattern by a phase specific to the transmitter.
