Wideband Equalization of Narrowband Receivers

In the fields of telecommunication and broadcasting, signal receivers often face the issue of out-of-channel interferers that affect the quality of the received signal, leading to loss of information, inaccuracy, signal disruption, and ineffective communication. Hence, there arises the necessity of a technology capable of addressing such matters. Current models are not particularly adept at estimating and eliminating the interferences that affect received signals. Attempts to deal with this invariably involve the application of signal-attenuating filters, but these solutions, in fact, cause significant signal loss, leading to overall degradation of the communication quality. This situation necessitated a more decisive and effective solution.

Technology Description

This invention includes methods and systems built to equalize reception in a first receiver. It involves receiving an input signal at two different receivers and then assessing the second receiver’s output response to estimate an out-of-channel interferer present in the input signal. Furthermore, it entails determining an estimate of the undesired in-channel response of the first receiver to the out-of-channel interferer within the input signal. The inventive aspect of the system is the mode of application by which the estimate of the undesired in-channel response of the first receiver to the out-of-channel interferer present in the input signal is applied to an output signal of the first receiver to substantial cancellation of any undesirable in-channel response stemming from out-of-channel interference. This solution proves to mitigate signal disruption.
