Patent ID: 8014468

Claim:
A first wireless device for transmitting information to a second wireless device via a wireless communication medium having a frequency bandwidth, the first wireless device comprising: a data source for providing data to be transmitted via the wireless communication medium to the second wireless device; an encoder linked to the data source for receiving the data to be transmitted and for coding the data, wherein coding the data comprises energy coding the data in M frequency subbands of the frequency bandwidth, wherein the energy coding comprises encoding the data by assigning a binary value to each one of the frequency subbands, wherein a value of the encoded data is based on which of the frequency subbands has energy present at a single point in time and the binary values assigned to the frequency subbands that have energy present at said single point in time, wherein a number of possible values encoded using the energy coding is greater than M; and an up converter for transmitting the coded data to the second wireless device via the wireless communication medium.
