Patent ID: 7920483

Claim:
An apparatus for optimizing a transmission mode of wirelessly transmitted data, the apparatus comprising: an first-transmission-mode selector capable of selecting a first transmission mode based at least in part on a predetermined channel database or a first channel characterization, or combinations thereof; an error-factor generator capable of generating an error factor based at least in part on a difference between an estimated performance characteristic of data signals transmitted according to the first transmission mode and an expected performance characteristic of data signals transmitted according to the first transmission mode, the generated error factor being a predetermined value X if the difference between the estimated performance characteristic of data signals transmitted according to the first transmission mode and the expected performance characteristic of data signals transmitted according to the first transmission mode is less than or equal to a predetermined difference and being a predetermined value X/N if the difference between the estimated performance characteristic of data signals transmitted according to the first transmission mode and the expected performance characteristic of data signals transmitted according to the first transmission mode is greater than the predetermined difference, in which N is based on the expected performance characteristic of data signals transmitted according to the first transmission mode; and a subsequent transmission mode selector capable of selecting a subsequent transmission mode based at least in part on the predetermined channel database, the error factor or a subsequent channel characterization, or combinations thereof.
