Transmitter, Communication Apparatus, Method and Computer Program for Transmitting Amplitude Shift Keyed Signals Using Multiple Transmit Antennas

Abstract:

A method of transmitting an amplitude shift keyed signal uses a multi-layered transmission over a plurality of transmit antennas with different precoding of different symbols for the respective layers. The method comprises obtaining a sequence of bits to be conveyed, keying the sequence of bits to a signal, precoding the signal to respective layer, and transmitting the precoded signal. A transmitter for transmitting the amplitude shift keyed signal, and a computer program for implementing the method are also disclosed.
