摘要: Examples of wideband spectrum sensing techniques for cognitive radio are provided. The permit undersampling (e.g., sub-Nyquist sampling) the band, which permits use more cost effective electronic components lower frequency analog-to-digital converters (ADC)). determination whether there any (or sufficient) sub-channels that exist in band to transmission, so only a portion less than entire is sampled. Detection decisions can be based at least partly on pair performance metrics appropriate sensing. These probability insufficient opportunities (P ISO ) and excessive interference EIO ).
