Spectrum Distribution in Cognitive Radio: Error Correcting Codes Perspective

摘要

Cognitive radio is a growing zone in wireless communication which offers anopening in complete utilization of incompetently used frequency spectrum: deprived of crafting interference for the primary (authorized) user, thesecondary user is indorsed to use the frequency band. Though, scheming amodel with the least interference produced by the secondary user for primaryuser is a perplexing job. In this study we proposed a transmission modelbased on error correcting codes dealing with a countable number of pairs ofprimary and secondary users. However, we obtain an effective utilization ofspectrum by the transmission of the pairs of primary and secondary users’data through the linear codes with different given lengths. Due to thetechniques of error correcting codes we developed a number of schemesregarding an appropriate bandwidth distribution in cognitive radio.
