Patent ID: 8284862

Claim:
A method for encoding data symbols in a transmitter of a wireless network, comprising the steps of: providing a set of data symbols to a transmitter to be transmitted, wherein each data symbols is selected from a set of modulation constellations; determining a sample-mean of the set of data symbols; shifting each data symbol by the sample-mean to obtain a shifted data symbol; multiplying the shifted data symbol by a first constant to obtain a scaled data symbol, wherein the first constant depends on a first function of the energy of the set of data symbols; adding a second constant to the scaled data symbol to obtain a mapped data symbol, wherein the second constant depends on a second function of the energy of the set of symbols; multiplying the sample-mean by a third constant to obtain a sample-mean mapped symbol; transmitting, over a channel, the set of mapped data symbols and the sample-mean mapped symbol as a resource block, wherein the steps are performed in the transmitter.
