Abstract
Official abstract text for this publication.
Disclosed are various embodiments that are directed towards distinguishing between various types of interference in an orthogonal frequency division multiplexing (OFDM) wireless communication system. According to some embodiments, the system receives a set of symbols encoded in a predetermined subcarrier activation pattern according to an OFDM protocol. The system may determine a plurality of time averaged interference values, each time averaged interference value corresponding to a respective subcarrier index expressed in the set of symbols. Then, the system may separate frequency-based interference from time-based interference according to the plurality of time averaged interference values.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: receiving, by processing circuitry, a set of symbols encoded in a predetermined subcarrier activation pattern according to an orthogonal frequency division multiplexing protocol, the predetermined subcarrier activation pattern including a pair of activated subcarriers of consecutive symbols, among the set of symbols, that are separated according to a maximum circular separation to facilitate a detection of interference between the…
