Abstract
A transmission method and a transmitter include one or more antennas for achieving several transmit antenna patterns for the transmission of a signal, and a receiver for receiving complex channel symbols at its input. To achieve a high transmission rate and good resistance to interference, the transmitter is configured to code the complex channel symbols by using orthogonally distributed channel resources into channel symbols such that a channel symbol to be transmitted using at least one antenna pattern during at least one channel resource unit is a linear combination of at least three modulation symbols. The invention also includes a transmitter for transmitting more than T complex modulation symbols during T channel resource units, wherein T is at least 2.
