Some wideband wireless links such as unmanned aerial vehicle (UAV) and satellite links have much wider bandwidth than that of high power natural or artificial interference. An idea of adaptive narrow band interference (NBI) cancellation based on different algorithms and structures aiming at wideband wireless links where bandwidth of interference is relatively narrow is posed here. All these theoretically...
A novel adaptive equalizer algorithm is proposed based on an array pattern synthesis algorithm, which provides a fast convergence speed with low complexity. By incorporating an interference suppression mechanism in the iterative procedure, the algorithm is able to achieve a performance that is very close to that of RLS algorithm. The proposed algorithm is demonstrated through computer simulation.
Motivated by the recent development on iterate-averaging (IA) for accelerating convergence rates of stochastic approximation algorithms, and widely linear (WL) processing for improving performance of the linear minimum mean-squared error (MMSE) multiuser receivers, in this paper, a widely linear IA affine LMS algorithm (WL IA-ALMS) for adjustment of the WL MMSE filter for multiple access interference...
Global position system (GPS) adaptive array antenna forms null beam to suppress the interference in order to communicate normally. The nulling beamforming model is actually an optimization technique. Because the traditional adaptive algorithms usually obtain the partial optimum solution, in this letter, we propose adaptive ant colony algorithm (AACA) can find the desired solution which is a global...
In th is paper, a robust algorithm for beamforming is presented, which is based on the RLS algorithm for adaptive beamforming, computer simulation and analysis demonstrate the performance of the proposed algorithm, which breaks through the traditional way, excess over the conventional RLS algorithm. The theoretical analysis and computer simulation results showed that the algorithm was effective.
The imperfect statistic and spectrum characteristics of direct spread spectrum signals will effect on the performance of narrow-band interference (NBI) suppression in DS/CDMA. To resolve this problem, an improved QR-decomposition-based least squares lattice (QRD-LSL) interpolator based on cycle-counteract (CYC) nonlinear processing is proposed. Applying the discrepancy of cycle correlation characteristics...
