Multiple-Access Interference Suppression for OFDM Systems
Researchers at Purdue University have developed a method to change the historical disadvantages of the Doppler Shifts into benefits. This method exploits Doppler Shifts caused by motion, which ultimately allows more information to be conveyed in a communication network. This performance increase is achieved by adding only a very small amount of structure to transmitted signals. This method applies to wireless multiple access systems.
