Patent ID: 8654872

Claim:
A method of transmitting a signal, said signal being composed of symbols and being transmitted by the use of a set of frequency subcarriers, said method comprising for at least one current symbol: defining an association of each element of a current information symbol vector, d i , with a subcarrier of said set of frequency subcarriers, determining a current modulation vector, d i , corresponding to addition of a transmitter correction vector, w i , to said current information symbol vector, d i , providing a transition between a previous symbol and said current symbol of continuity of a specified order, n, in time domain, and modulating said set of frequency subcarriers with elements of said current modulation vector, d i , in accordance with said association; wherein the transmitter correction vector w i is equal to: w i =−Pd i +Q d i-1 , or the current modulation vector d i is equal to: d i =( I−P ) d i +Q d i-1 , where P and Q are functions of A and Φ, A is a matrix having elements of a form corresponding to k m , Φ is a diagonal matrix having elements of a form corresponding to e jαk , d i-1 is a previous modulation vector, k is an OFDM subcarrier index, m is an integer, and α is an arbitrary value.
