Secure wireless communication using rate-adaptive codes
Data are communicated in a wireless network, between a transmitter and a receiver. The transmitter estimates a first channel response between the receiver and the transmitter, and generates a first key based on the first channel response. The data are encoded at the transmitter using a rate-adaptive code to produce encoded data, and scrambled using the first key before broadcasting. Subsequently, the receiver can estimate a second channel response to generate a second key to be used to descramble the broadcast data.
