A convex projections method for improved narrow-band interference rejection in direct-sequence spread-spectrum systems
نویسندگان
چکیده
A method is presented for enhancing the narrowband interference rejection capability of direct-sequence spread-spectrum systems employing an adaptive notch filter. The method, based on projection onto convex sets, restores that part of the spread-spectrum signal distorted by the filter. Simulation results are presented which show the output bit-error rate (BER) improvement gained by using the signal restoration scheme.

Interference Rejection in DS Spread Spectrum Systems Using Nonlinear Interpolation Lattice Filters
An Mth-order adaptive lattice filter automatically generates all M of the outputs that would be provided by M separate transversal filters. This feature can effectively suppress the narrow-band interference (NBI) of time-varying bandwidth in direct-sequence (DS) spread-spectrum systems for which the order of the interference rejection filter that achieves the optimal performance is unknown and ...

The influence of microwave oven interference on IEEE802.11 Wireless Local Area Network (WLAN) performance is a significant factor because they share common spectrum in the 2.400 2.4835 GHz Industry, Science, and Medicine (ISM) band. FCC regulations permit radiated power of up to 1 watt in this band provided spread spectrum techniques are employed. Spread spectrum methods facilitate multiple use...
متن کاملNarrow-Band Interference Suppression in CDMA Spread-Spectrum Communication Systems Based on Sub-Optimum Unitary Transforms
In this paper, we present several unitary transform-domain filtering techniques based on KarhaunenLoeve Transform (KLT) for narrow-band interference rejection in CDMA communication systems. The reason for selecting the KLT is that it is an optimum unitary transform in the sense of packing the energy of the narrow-band interference. As a result after applying this transform, a small portion of t...
متن کاملInterference Rejection Techniques in Spread Spectrum Communications
Spread spectrum communication systems have many applications, including interference rejection, multiple accessing, multipath suppression, low probability of intercept transmission, and accurate ranging. Of all the potential applications, the ability of a spread spectrum system to withstand interference, both intentional and unintentional, is probably its greatest asset. Of course, any spread s...
