Abstract
In embodiments of frame boundary detection, a data signal that includes a plurality of different synchronization signals is received. Symbol boundaries of orthogonal frequency-division multiplexing (OFDM) symbols are detected in the data signal based on signal characteristics of the OFDM symbols. The characteristics of the OFDM symbols include cyclic shift properties of the OFDM symbols, such as the characteristic that a first portion of an OFDM symbol is the same as a last portion of the OFDM symbol. One or more of the plurality of different synchronization signals in the data signal can be located using the detected symbol boundaries of the OFDM symbols to determine a frame boundary of a data frame in the data signal.
