Abstract:
1. A method for adaptively selecting a high-frequency communications mode of a dual-mode device, the method comprising: receiving a signal through a first communications channel at a first dual-mode device; determining a first condition associated with a length of a high frequency communications channel at the first dual-mode device based on a second condition associated with a length of the first communications channel and a reciprocal relationship between the first communications channel and the high frequency communications channel; comparing the length of the high frequency communications channel to a threshold; and selecting between an orthogonal frequency division multiplexing (OFDM) mode and a single carrier (SC) modulation mode based on the comparing to communicate through the high frequency communications channel, wherein the OFDM mode is selected when the length of the high frequency communications channel exceeds the threshold and the SC modulation mode is selected when the length of the high frequency communications channel is below the threshold.
