Genetic Algorithm (GA) assisted beamforming techniques are proposed as an alternative to conventional beamforming algorithms. The design of the corresponding GAs is highlighted and the achievable performance is characterised in terms of the Signal-to-Interference Ratio (SIR) and the Signal-to-Interference plus Noise Ratio (SINR). It is demonstrated that an attractive SINR versus complexity trad...

Reasoning about concurrent processes requires distinguishing communication from interference, and is especially difficult when the means of interaction change over time. We present a new logic for the π-calculus that combines temporal and separation logic, and treats channels as resources that can be gained and lost by processes. The resource model provides a lightweight way to constrain interf...

The N + 1 user, 1 × N single input multiple output (SIMO) Gaussian interference channel where each transmitter has a single antenna and each receiver has N antennas is studied. The sum capacity within O(1) is characterized for the symmetric case where all direct links have the same signal-to-noise ratio (SNR) and all undesired links have the same interference-to-noise ratio (INR). The gap to th...

The existing mobile communication system suffer from problems like frequency selective fading and multi-path signals, multiple access interference due to imperfect nonorthogonal codes and narrow band interference due to coexisting systems. Multi-carrier Code Division Multiple Access (MC-CDMA) technique can combat these problems efficiently owing to its inherent properties. The objective of this...

A deficit in "interference control" is commonly found in adults with Attention Deficit Hyperactivity Disorder (ADHD). This has mainly been interpreted as difficulties in inhibiting inappropriate responses. However, interference control involves processes other than simply the ability to inhibit. Consequently, we used sophisticated analysis to decipher the additional processes of interference co...

Results from simulation model of an 802.11 WLAN system that suffers in performance due to interference problems are presented. The effect on performance due to change in fragmentation thresholds are shown in terms of traffic sent, received, and retransmission attempts with and without RTS/CTS mechanism. It is shown that for the modeled system a fragmentation threshold value of 256 to 500 octets...

In this paper, we propose an information theoretic waveform design algorithm for multiple-input multiple-output radars to support co-existence with a communication system under additional constraints on interference reduction from the clutter, minimizing the peak-to-average-power ratio and correlation levels of the radar. Numerical results are presented which show the performance of the propose...

Indexing terms : adaptive algorithm, system identification Abstract : In the presence of input interference, the Wiener solution for impulse response estimation is biased. In this Letter, it is proved that bias removal can be achieved by proper scaling the optimal filter coefficients and a modified least mean squares (LMS) algorithm is then developed for accurate system identification in noise....
