Abstract :
SAR codes are designed for transmission by a portable wireless device to provide high reliability and data rates on a wireless channel, while maintaining low human exposure to electromagnetic radiation. We provide design criteria and examples of SAR codes and show that a 3 dB reduction in exposure is within reach on some devices versus standard single-antenna methods or spacetime codes. This reduction in exposure can be used to boost the transmitted power and extend the usable range of a portable device while maintaining a prescribed exposure level.
