Abstract
Official abstract text for this publication.
Methods and systems are disclosed for frequency-domain frame synchronization for multi-carrier communication systems. Received signals are sampled and converted into frequency domain components associated with subcarriers within the multi-carrier communication signals. A sliding-window correlation (e.g., two-dimensional sliding window) is applied to the received symbols represented in the frequency domain to detect frame boundaries for multi-carrier signals. The sliding-window frame synchronization can be applied by itself or can be applied in combination with one or more additional frame synchronization stages. The disclosed embodiments are particularly useful for frame synchronization of multi-carrier signals in PLC (power line communication) systems.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for detecting a frame boundary in multi-carrier signals, comprising: receiving input signals from a communication medium; digitizing the input signals to generate digital samples; generating frequency components for the digital samples, the frequency components being associated with received symbols within the input signals; determining a frame synchronization correlation value based upon a multiplication of frequency components for a subset w…
