Self-encoded spread spectrum (SESS) has been shown to provide significant advantages for communications in fading or jamming environments. With the proliferation of GNSS such as GPS, Galileo, and GLONASS, it would be desirable to bring the advantages of SESS to these systems. In order to do this the iterative detector in a receiver must be able to provide a high-quality timing estimate. Presented...
This article proposes a new method of maintaining synchronization of carrier for the correlation receiver. We use PSK of fifth phase for this telecommunication system. However, we can apply this method for the correlation receiver of any other demodulation. As usual method for the synchronization, there is DLL (Delay Lock Loop). However we thought that we can directly find the value of phase difference,...
This article proposes a new method of maintaining synchronization for the correlation receiver. I use PSK of fifth phase for this telecommunication system. However, we can use this method for the correlation receiver of any other demodulation. As usual method for the internal synchronization, there is DDL (Delay Lock Loop). But I thought that we can directly calculate the value of phase difference,...
A new radio ranging system based on pseudo-random binary-phase code and linear frequency combined modulation is presented. An improved signal processing method of the correlation detection of cyclic autocorrelation function is given and applied to the ranging system. It is proved to be equivalent to the spectral correlation method. The ranging performance and anti-noise ability are simulated and analyzed...
Orthogonal frequency division multiplexing (OFDM) is the modulation scheme of choice for digital video broadcasting-handheld (DVB-H) which is required to operate under high mobility conditions resulting in significant Inter-Carrier Interference (ICI). Under these conditions, the conventional one-tap per subcarrier channel estimation and equalization is suboptimal since it does not account for ICI...
