Abstract:
1. A method to be used with first and second devices where the first and second devices are capable of communicating using a subset of different modulation schemes wherein the subset includes at least first and second different modulation schemes, the method for optimizing transmission of data from the first device to the second device, the method comprising the acts of: at the first device, when data is to be transmitted from the first device to the second device: receiving at least a portion of a trigger signal from the second device wherein the transmitted trigger signal includes data transmitted using a sequence of at least two of the modulation schemes from the subset, the portion of the trigger signal received being a received trigger signal; analyzing the received trigger signal to identify one of the modulation schemes from the subset as a function of the received trigger signal as an initial modulation scheme to be used to transmit data to the second device; and transmitting the data from the first device to the second device using the initial modulation scheme.
