Abstract:A new RF modulation scheme based on a frequency-offset technique is presented. Instead of using sinusoidal carriers, pure noise is applied as information bearer. The transmitted signal is a combination of modulated noise and unmodulated noise acting as a reference. The reference and modulated signals are separated by a frequency offset Δf which is much smaller than the transmission bandwidth. When using the technique, very large processing gains can be obtained which provides robustness in interference-prone environments. In addition, very simple transceiver implementations result. The paper shows both analytical and experimental results.
