Create a PN sequence of length 8. Perform BPSK modulation on the data (0 → -1, 1 → +1). Spread the BPSK modulated signal using the PN sequence. Modulate the spread signal using a BPSK carrier. Plot ...
STD-502-R 2.4 GHz transceiver which uses direct sequence spread spectrum (DSSS) modulation and a true diversity circuit, enabling reliable communications even in the congested 2.4 GHz band. The ...
Abstract: The coherent direct-sequence spread spectrum (DSSS) modulation is a very attractive modulation technique for military communication systems, mainly due to its resistance to interference and ...
Amiccom released 2.4GHz direct-sequence spread-spectrum wireless chip in June 2020, named A7157, which supports FSK and DSSS modulation operation modes. In FSK mode, A7157 is a high-speed (4Mbps) RF ...
Chaotic DSSS-based underwater acoustic communication using Logistic map for secure BPSK modulation, Doppler shift compensation (±10 m/s), and robust performance in noisy, dynamic channels. MATLAB ...
This article investigates the demodulation capabilities of a DSSSsuper-regenerative receiver. Starting from the general expressionthat characterizes the receiver's behavior, we demonstrate that afew ...
The MU-D1-R operates in the U.S. ISM band frequencies (902 to 928MHz) and is designed to be embedded in wireless connected systems. This radio modem was developed for industrial applications that ...
Diverse well describes the myriad digital modulation schemes used in modern voice and data communications. The alphabet soup of terminology extends well beyond the familiar QAM and GMSK fundamentals ...
