WIDEBAND DIGITAL SPECTROMETER

摘要

A processor, comprising a first data input configured to receive a stream of samples of a first signal having a spectral space, the stream having a data rate of at least 4 GHz; a second data input configured to receive a stream of samples of a second signal; a multitap correlator, configured to receive the first stream of samples and the second stream of samples, and producing at least one correlation output for each respective sequential sample of the first signal received; and a programmable control configured to alter a relationship of the stream of samples of the first signal and the stream of samples of the second signal, to thereby select, under program control, an alterable correlation output.

主权项

1. A radio transceiver system for receiving communications in a band concurrently with transmissions from a transmitter transmitting in the band, comprising:
(a) an input port, configured to receive a first signal comprising the communications in the band and the transmission in the band from the transmitter; (b) a receiver, having a dynamic range, (c) a plurality of analog time delay elements each receiving an analog representation of the received first signal, which are selectively weighted and combined to produce a combined analog signal; (d) a digitizer producing a digitized signal from the combined analog signal; and (e) a processing subsystem, configured to:
control a respective weight of respective ones of the plurality of analog time delay elements in dependence on the digitized signal, to achieve a second signal representing at least partial cancellation of the transmission in the band while preserving the communications in the band;digitally cancel at least a portion of a residual transmission in the band in dependence on at least digitized signal; and (f) an output port configured to communicate the received communications.
