TIMING SYNCHRONIZATION AND CHANNEL ESTIMATION AT A TRANSITION BETWEEN LOCAL AND WIDE AREA WAVEFORMS USING A DESIGNATED TDM PILOT

摘要

Systems and methods are provided for channel estimation and timing synchronization in a wireless network. In an embodiment, a method is provided for time synchronization at a wireless receiver. The method includes decoding at least one TDM pilot symbol located at a transition between wide and local waveforms and processing the TDM pilot symbol to perform time synchronization for a wireless receiver. Methods for channel estimation at a wireless receiver are also provided. This includes decoding at least one TDM pilot symbol and receiving the TDM pilot symbol from an OFDM broadcast to facilitate channel estimation for a wireless receiver. ® KIPO & WIPO 2009
