2 Literature Survey

2 Literature Survey Normally, the available channels used by several systems may be overlapped in the frequency domain. A non-overlapped channel can be selected by a method of channel control to improve the capability of anti-interference. But it is very important to ensure the stability of the system when the channel is controlled. In this paper, we used the results of previous studies [1,3,6,8] and proposed a simulation model of 2.4 GHz-band network. With our model, the interference in the whole system model is was simulated when the channels are were occupied by users who used a single or multiple systems.

4 Proposed Method

4 Proposed Method So that the bit error rate is high because its channels overlapped ones of .other two systems. With our NCC mechanism, the bit error rate will be low as a result of channels of Bluetooth make frequency hopping transmission according to regulations by this mechanism.

6 Conclusion

6 Conclusion In this paper, we propose that the NCC mechanism jointly optimizes communication and controls of the systems. By using our NCC mechanism, we effectively reduced interference from co-existence of the channels and effectively reduced the BER. The improvement effect of the communication performance is obvious, especially when numerous consumers accessed to the system simultaneously.
