Title: WIRELESS COMMUNICATION SYSTEM AND TRANSMITTER
Abstract:
Provided is a wireless communication system provided with a first transmitter and a second transmitter, wherein the first transmitter generates an A-series transmission signal and a B-series transmission signal orthogonal to the A-series transmission signal when a first bit sequence is inputted and a first initial value is imparted, the A-series transmission signal and B-series transmission signal being transmitted from different antennas, the second transmitter generates the A-series transmission signal and B-series transmission signal when the first bit sequence is input and the first initial value is imparted, generates a C-series transmission signal differing from the A-series transmission signal, and generates a D-series transmission signal orthogonal to the C-series transmission signal when a second initial value differing from the first initial value is imparted, the C-series transmission signal and D-series transmission signal being transmitted from differing antennas, and the first initial value is imparted to the first transmitter and the second initial value is imparted to the second transmitter.
