Abstract:
1. A method, comprising: determining a physical carrier-to-interference plus noise ratio associated with a wireless channel between a first wireless communication device and a second wireless communication device; performing channel estimation of the wireless channel to obtain a channel response for the wireless channel; determining a channel margin based on the channel response; subtracting the channel margin from the physical carrier-to-interference plus noise ratio to obtain a discounted physical carrier-to-interference plus noise ratio; comparing the discounted physical carrier-to-interference plus noise ratio with a corresponding ideal physical carrier-to-interference plus noise ratio for an ideal non-fading wireless channel; and selecting a modulation and encoding scheme to be used for wireless communication between the first wireless communication device and the second wireless communication device based on the discounted physical carrier-to-interference plus noise ratio.
