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