Abstract:
1. A method of selecting operational parameters for transmitting a signal over a communication channel of a communication network, the method comprising the steps of: (a) determining RF conditions on the communication channel from a received signal transmitted over the communication channel; (b) selecting a preliminary set of parameter values for the operational parameters based on the RF conditions determined from the received signal; (c) using the preliminary set of parameter values to identify candidate sets of parameter values as potential candidates for transmitting the signal, an expected performance value being associated with each of the candidate sets of parameters, wherein determination of the expected performance value is independent of the RF conditions determined from the received signal; (d) selecting from among the candidate sets of parameter values a selected set of parameter values having the expected performance value indicating a highest expected performance among the candidate sets of parameter values, such that selection of the selected set of parameter values from among the candidate sets of parameter values is independent of the RF conditions determined from the received signal; and (e) transmitting the signal on the communication channel using the selected set of parameter values.
