A High Efficiency Spread Spectrum Scheme Using Approximate Orthogonal Complex Sequences
This paper presents a high efficiency spread spectrum scheme using approximate orthogonal complex (AOC) sequences. In this scheme, the 64 AOC sequences picked up from 8 complex sequences space are employed for spreading spectrum. In modulation, 6 input bits is used to select one AOC sequence, and the selected sequence is then phase-rotated by another 2 input bits. In demodulator, a complex corr...
متن کاملDesign of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications
This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...
متن کاملSpread spectrum and Pseudonoise Sequences
• Spread Spectrum multiple access (SSMA): In spread spectrum, the transmission bandwidth of the signals is several orders of magnitude greater than the minimum bandwidth required for transmitting a given piece of information. However, many users can share the same spread spectrum bandwidth without interfering with one another. Spread spectrum uses encoding techniques that are different than the...

متن کاملA High Performance Spread Spectrum Clock Generator Using Two-Point Modulation Scheme
A new spread spectrum clock generator (SSCG) using two-point delta-sigma modulation is presented in this paper. Not only the divider is varied, but also the voltage controlled oscillator is modulated. This technique can enhance the modulation bandwidth so that the effect of EMI suppression is improved with lower order ġĢ modulator and can simultaneously optimize the jitter and the modulation ...
