It is compliant with the BLE 4.2 and 802.15.4 PHY specifications, and supports 1Mbps GFSK and 250Kbps O-QPSK modulation and demodulation. It can be combined either with the Bluetooth Smart baseband ...

In the case of carrier-recovery in which coherent demodulation is to be performed on QAM-type signals, the Costas loop has found wide-spread use as an unbiased low-variance practical solution. It can ...

Abstract: Aiming at realizing high-efficiency distributed strain sensing through optical frequency domain reflectometry (OFDR), this paper introduces a fast demodulation algorithm to determine ...

Theoretically the proposed demodulation scheme is not influenced by the zeros of the Bessel functions, and can keep a good performance in a wide range of modulation depth. It is compared with ...
