Abstract
A method for detecting the digital quality of a radio signal includes: receiving a radio signal including a digital portion modulated by a series of symbols each including a plurality of samples; computing correlation points between endpoint samples in cyclic prefix regions of adjacent symbols; and using the correlation points to produce a digital signal quality metric. Receivers that implement the method are also provided.
Claims20
A method comprising:
- receiving a radio signal including a digital portion modulated by a series of symbols each including a plurality of samples;
- computing correlation points between endpoint samples in cyclic-prefix regions of adjacent symbols;
- and
- using the correlation points to produce a digital signal quality metric.
1 more element
An apparatus comprising:
- a radio receiver including an input for receiving a radio signal having a digital portion modulated by a series of symbols, each including a plurality of samples, and a processor for computing correlation points between samples in cyclic-prefix regions of the symbols to produce a digital signal quality metric.
A method comprising:
- receiving a radio signal including an analog modulated portion;
- digitally sampling an analog modulated portion of the radio signal to produce a plurality of samples;
- using a ratio between an average magnitude and an RMS magnitude of a block of the samples to compute an analog signal quality metric.
