In this paper comparison of the two innovative signal processing methods for analysis of both EEG and EMG biomedical signals is in short presented. The reason for that is caused by the fact, that nowadays the broad analysis of various biomedical signals is extremely popular. The first method presented in this paper relies on kernel density estimators application. Implementation of such method enables construction of densitograms for the examined bio-signals. One of the biggest advantages of this method is that it allows to obtain statistically filtered signals, which results in making the whole signal processing task significantly quicker. The second method described in this paper is based on basic mathematical operations only. Despite its simplicity the whole process can be implemented on almost any hardware platform, including those with very limited computational capabilities. Also it makes the task quick. In accordance with the conducted experiments - the method is also efficient and as it can also be implemented on embedded platform and the algorithm can be rewritten in any programming language, the potential application of this method is wide.

This paper focuses on evaluating the performance of two aperture averaging methods used for compensating the effects of the air turbulence in free space optical (FSO) communications. These methods are based on using a concentration lens and spherical concave mirrors (SCM). The preliminary experimental results show that the quality of the received signal in terms of the Q-factor and the scintillation index is moderately improved when employing a lens in comparison to SCM for all turbulence regimes. However, these results were obtained with different collection areas and focal points. Therefore, a more rigorous approach using lens and SCM with the same aperture diameters and focal lengths needs to be adopted to ensure conclusive results.
