| Summary: | New cognitive radio channel model is the combination of the interweave channel and the interference channel.By introducing the switch concept,the spectrum hole sensing was combined the channel model.So a new cognitive radio two-user channel model with partial knowledge of the primary messages at the cognitive transmitter was proposed.First,the channel between the primary user and the second user was modeled as a compression channel and introduced the compression rate.Then,the channel capacity was analyzed and calculated.Finally,numerical results illustrate the validity of the new channel model and the advantage of its capacity. |
