An algorithm using compressive sensing to blindly detect frequency hopping signals corrupted by white Gaussian noise is presented. The samples obtained through compressive sensing effectively maintain structures and information of the original signal, so detection tasks of the original signal could be solved by directly processing the sampling values. The algorithm is based on the difference in numerical...
Aim at the problem of the adjacent cell interference in LTE (long Term Evolution) system, a distributed pre-coding technology based on singular Value Decomposition (SVD) was presented, which need not to exchange user date between the cooperation base station, just need to know the channel state information (CSI) from the baste station to all users (include expected users and adjacent cell users)....
Aiming at the problem of blind source separation of the communication signals, we propose a step size optimization equivariant adaptive source separation via independence (SO-EASI) algorithm basing on the EASI block based algorithm. This algorithm adjusts the step-size by the steepest descent method and thereby greatly increases its convergence speed whatever value the step-size is initialized. Simulation...
