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.
