Wideband low latency repeater and methods

摘要

A signal repeater (200) includes a signal processing part (202) and a signal repeating part (204). The signal processing part includes a converter (300) configured to receive an input signal and to convert the input signal into quadrature signals, and a processor (302, 304, 306) configured to process the quadrature signals to determine one or more characteristics of the input signal, and to compare the one or more characteristics of the input signal and a plurality of predetermined characteristics to generate a comparison result. The signal repeating part (204) is configured to selectively repeat the input signal as a repeated signal in accordance with the comparison result.

1. A signal repeater comprising:
a signal processing part comprising:
a converter configured to receive an input signal and to convert the input signal into quadrature signals comprising a plurality of polyphase samples; anda processor configured to:
calculate magnitudes of each of the plurality of the polyphase samples, and calculate an average magnitude based on the calculated magnitudes, andcalculate frequencies of each of the plurality of polyphase samples by conjugate-multiplying, and calculate an average frequency of each of I and Q portions based on the calculated frequencies; andcompare the average magnitude and the average frequency of the input signal with a plurality of predetermined characteristics to generate a comparison result; and a signal repeating part configured to selectively repeat the input signal as a repeated signal in accordance with the comparison result, wherein the processor is configured to calculate the magnitude of the input signal according to an equation defined as Magnitude=L+S/2, where L=largest of |I| or |Q| of the quadrature signals, and S=smallest of |I| or |Q| of the quadrature signals.
