Title: A METHOD FOR EXPLOITING PREAMBLE WAVEFORMS TO SUPPORT DEVICE AND NETWORK FUNCTIONALITIES IN WIRELESS SYSTEMS
Abstract:
The frame preamble in current wireless systems is designed to facilitate various PHY-layer functions, including frequency offset estimation and frame detection. However, this preamble is assumed to be constant and is seldom used to convey any frame-specific bits. Embedding information into the preamble can open the door for new PHY-layer applications. P-modulation, a method that enables an OFDM-based wireless transmitter to embed frame-specific bits into the frame preamble to accomplish PHY-layer applications (while remaining backward-compatible with legacy receivers), is presented.
