Abstract: A method of operating a radio transmitter configured to transmit at least one sequence of logic values by transmitting transmission signals selected in a constellation diagram having a certain cardinality comprises selecting said transmission signals out of a first subset of transmission signals in said constellation diagram, said first subset comprising a first number of transmission signals, and a second subset of transmission signals in said constellation diagram, said second subset comprising a second number of transmission signals, wherein. The transmission signals in the second subset of transmission signals have an energy higher than the transmission signals in the first subset of transmission signals. The sum of said first number of transmission signals and said second number of transmission signals is less than said cardinality.
