Methods and apparatuses for processing a signal that is transmitted with a reduced peak to average power ratio are described. The processing includes pre-encoding a stream of data in order to reduce peak to average power ratio of the transmitted signal by applying (1650) a symbol constellation extension projection to at least one symbol in a constellation used as part of the transmitted signal, the symbol constellation extension projection having an outward angular region from an original position for the at least one symbol in the constellation, the outward angular region defined by a value for an angle between a first boundary and a second boundary for the outward angular region, the value for the angle based on the constellation and a code rate for the stream of data. |
