Time-Domain Spreading And Frequency-Domain Spreading for Delay-time/Code Division Multi-Access
—The uplink (mobile-to-base) bit error rate (BER) performance is significantly degraded due to the multi-access interference (MAI). Recently, we have proposed a new hybrid multi-...

Spread Spectrum Visual Sensor Network Resource Management Using an End-to-End Cross-Layer Design
—In this paper, we propose an approach to manage network resources for a direct sequence code division multiple access (DS-CDMA) visual sensor network where nodes monitor scenes ...

Blind Detection of Spread Spectrum Flow Watermarks
— Recently, the direct sequence spread-spectrum (DSSS)-based technique has been proposed to trace anonymous network flows. In this technique, homogeneous pseudo-noise (PN) codes...

On the performance of concatenated convolutional code and Alamouti space-time code with noisy channel estimates and finite-depth
Abstract--In this paper, performance of the Alamouti spacetime code (STC) [1] and performance of the concatenation between the convolutional code and the Alamouti STC are derived. ...

2D Markovian SS codes flatten time-frequency distribution of signals in asynchronous Gabor division CDMA systems
We propose a Gabor division (GD)-CDMA system which permits time and frequency offsets. Negatively correlated time- and frequency-domain spreading codes have shown to reduce the va...
