Patent ID: 7110464

Claim:
A method for generating space-time codes, the method comprising: computing a baseband design criteria for determining a diversity advantage and a coding advantage achieved over block fading channels; translating the baseband design criteria into a binary rank criteria for modulated codes corresponding to the space-time codes; and outputting the space-time codes according an algebraic framework derived from the binary rank criteria, wherein the binary rank criteria specifies that for every non-zero code word c∈C, ∑ m = 1 M ⁢ rank ⁡ ( c ⁡ [ m ] ) ≥ d , the rank is over a binary field F and d is the largest possible integer, the space-time code C achieving a diversity level of at least dL n L r being the number of the plurality of receive antennas, m representing the number of blocks per code word.
