Patent ID: 8670498

Claim:
A method of randomizing interference in space frequency block coding (SFBC) communication, the method comprising: performing SFBC encoding on a set of four symbols, wherein the SFBC encoding includes mapping the set of four symbols across a set of four subcarriers and across a set of four antennas according to a first frequency assignment pattern in a serving cell; transmitting the set of four symbols using the first frequency assignment pattern over the set of four antennas; wherein the first frequency assignment pattern maps symbols to the set of four subcarriers and the set of four antennas, wherein an orthogonal set of the four symbols is manned to each subcarrier, each symbol of the orthogonal set is assigned to a different antenna of the set of four antennas, and wherein the set of four subcarriers to which each of the orthogonal sets of symbols are mapped in the first frequency assignment pattern are a permuted set of four subcarriers to which orthogonal sets of symbols are mapped in a neighbor cell.
