Binary Offset Carrier modulation for a 38.4 kbps radio

The Binary Offset Carrier (BOC) was designed to add new signals in the existing radio frequency bands of the Global Navigation Satellite System (GNSS). The BOC modulation was such designed that the spectrum has nulls at the centre frequency. Thus it provides frequency re-use. With the spectrum getting crowded day by day, the concept of BOC modulation can be applied on the existing radio frequency bands in the radio. The two sidebands of BOC give redundancy and hence give definite advantage in signal acquisition, code tracking, carrier tracking and data demodulation. In this paper we give a brief overview of our implementation of BOC in a 38.4kbps radio.
