Abstract
Official abstract text for this publication.
Embodiments of a wireless device and method for transmitting a packet comprising one or more orthogonal frequency division multiplexed (OFDM) transmission symbols are generally described herein. In some embodiments, the wireless device may be configured to map data to active tones and map zeroes to nulled tones of a set of OFDM tones to generate an OFDM symbol comprising both the active and the nulled tones. The number of active and nulled tones may be based on a nulling factor. The OFDM symbol may be down-clocked to generate an OFDM transmission symbol for transmission over a reduced transmission bandwidth. Accordingly, low power may be used for very low data rate transmissions, which may be suitable for sensor devices.
First claim
Opening claim text (preview).
What is claimed is: 1. A wireless device for transmitting a packet comprising one or more orthogonal frequency division multiplexed (OFDM) transmission symbols, the wireless device configured to: map data to active tones and map zeroes to nulled tones of a set of OFDM tones to generate an OFDM symbol comprising both the active and the nulled tones, the number of active and nulled tones being based on a nulling factor; and generate an OFDM transmission symbol for transmission ove…
