Disclosed are a wireless transmission device, wireless receiving device, and method for transmitting encoded data with which power consumption can be reduced at the receiving end in accordance with reception conditions, while resource-saving is maintained by employing an erasure correcting code. Also provided are methods of preparing these molecules, and kits to perform the methods. System gain is then adjusted, and the companding ratio may be further adjusted by adjusting one of the kneepoints relative to another. Also, by having the thermal diffusion barrier act as a solder dam, an additional deposition or etching process can be omitted. The devices come in a variety of configurations including sheet, rolled sheet, folded sheet and polygonal solids including extruded shapes.
