Abstract:
Wireless networks that use orthogonal frequency division multiplexing require a receiving device to accurately acquire and maintain synchronization with a transmitting device with respect to carrier and sampling frequency for coherent demodulation. Described herein are techniques for enabling such synchronization using pilot signals with reduced transmission overhead.
