Researchers at Princeton University and Drexel University have developed a new
process for signal processing related to wireless communications, specifically
to provide blind CFO estimation and symbol recovery. Princeton is
currently seeking industrial collaborators to commercialize this technology.
This invention addresses the problem of carrier-frequency offset
estimation in distributed antenna systems. Existing methods for
accomplishing this task require the use of training symbols, which must be
transmitted to the receiver, thereby using up valuable bandwidth and power
resources. The principal novelty of this invention is that it accomplishes
this task blindly, without the need of resorting to training data.
It is anticipated that this new
approach will allow for greater energy and bandwidth efficiency in mobile
wireless data transmission. This invention would most likely be beneficial
as software for an access point or base station in a mobile wireless
network. Patent protection is pending.
