Mechanisms based on frequency hopping have been widely used in many
applications such as the personal communications services and the wireless networks. In
this paper, we describe, simulate and implement a frequency hopping spread spectrum
transceiver. A baseband model for Bluetooth Frequency Hopping Transceiver is
presented. Several modulation techniques, such as QPSK, 8-FSK and 16-QAM, are
exploited to achieve a bit rate of 2Mbps, 3Mbps and 4Mbps respectively. We clacutate
the bit error rate of the described transceiver model with the aid of Monte Carlo analysis
technique. The proposed model is then implemented using the C6713 floating-point DSP.
The functionality of the implemented system is tested via Real Time Data Exchange
(RTDX). |
