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 ...

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 ...

Using sophisticated DSP techniques, the High Data Rate Modulator IP Core can generate almost any modulation scheme up to 8 bits wide, such as (but not restricted to) BSPK, QPSK, offset- QPSK, ...

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