Wideband technology has been applied to many wide bandwidth applications when there is a need to send much different information in a short time from one point and received from another point in high precision and accuracy. A wideband receiver reports a signal without tuning if the signal is within the input bandwidth. The analog Instantaneous Frequency Measurement (IFM) receiver has been used for decades to cover a very wide input bandwidth and report one accurate frequency on a short pulse at a time. The digital IFM use a high sampling rate ADC to operate in a wide bandwidth, Hilbert transform to produce two output channels that have a 90-degree phase shift and autocorrelation to measure the frequency by comparing different delayed lines of the input signal with the original one. This research discusses the sensitivity of the existing digital IFM receiver and optimizes the Hilbert transform as well as the autocorrelation architectures to report a fine frequency within a noisy wide bandwidth environment after improving its sensitivity.
