    Separation of underdetermined mixtures is an important problem in signal processing that has attracted a great deal of attention over the years. Prior knowledge is required to solve such problems and one of the most common forms of structure exploited is sparsity. Another central problem in signal processing is sampling. Recently, it has been shown that it is possible to sample well below the Nyquist limit whenever the signal has additional structure. This theory is known as compressed sensing or compressive sampling and a wealth of theoretical insight has been gained for signals that permit a sparse representation. In this paper, the proposed study introduces undertermined BSS algorithm with unifying frequency texture pattern and sparse representaion by using a compressed...

    Consider the pulse shaping filter created by using a truncated sinc function. Assume that we are operating ten times oversampled (that is 10 samples for every Nyquist sample, or 9 zeros between each Nyquist sample): (a) Plot the pulse shaping filter that spans the space of -3 to 3 Nyquist samples. Warning: matlab uses sinc(x) = sin(x)/x rather than sin(pi*x)/(pi*x). (b) By using this sampled truncated sinc, construct and plot the energy spectral density for this pulse shaping filter. (c) Plot the pulse shaped output signal of the oversampled signal for the three BPSK symbols at Nyquist, given by the oversampled sequence: {1,0,0,··· ,0,1,0,0,··· ,0,−1}.

    Hello! I need a little work done on a plug-in for the audio editor Audacity. It's written in Nyquist, which is based on Lisp. The plugin analyzes audio data for files open in Audacity, and then prints that data to a .txt or .csv file. There are three modifications that I need. The first (and simplest!) is the most important. I could live without the others, for now. 1) I need the plugin to print much LESS data to the exported file. I really only need a small part of the data analysis exported. All I need is the "stereo peak" and "stereo RMS" in that export, but I am hesitant to go in and start deleting code. 2) The program can be run in Audacity as a batch process, so it can analyze a large number

    Abstract: Pulse shaping is examined as a means to improve the performance of a differential offset quadrature phase-shift keying system in a bandwidth-constrained environment. Through optimization with respect to a composite Nyquist criterion, the derived pulse shapes have comparable performance to a pi/4-differential quadrature phase-shift keying in an additive white Gaussian noise (AWGN) channel and better performance in a hard-limited AWGN channel Published in: IEEE Transactions on Communications ( Volume: 54, Issue: 10, Oct. 2006 ) Page(s): 1731 - 1734 Date of Publication: 16 October 2006 Print ISSN: 0090-6778 INSPEC Accession Number: 9137936 DOI: 10.1109/TCOMM.2006.881349 Publisher: IEEE Sponsored by: IEEE Communications Society
