DATA COMMUNICATION METHOD AND WIRELESS COMMUNICATION NETWORK

摘要

PROBLEM TO BE SOLVED: To provide a method of communicating data safely and securely in a wireless network between a transmitter and a receiver.

SOLUTION: A transmitter 101 estimates a first channel response between a receiver 102 and the transmitter at 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. The encoded data is scrambled using the first key before broadcasting before being broadcasted. Subsequently, the receiver 102 can estimate a second channel response to generate a second key to be used to descramble the broadcasted data.
