Costas Loop for coherent demodulation of GMSK Hello, i want do do carrier recovery using costas loop(BPSK based) for coherent demodulation of GMSK. Has anybody tried it? If yes, please help me out. Thanks and Regards, Sonali ... 13 Aug 2010 17:56
Wavelets Hi I would like to develop a CDF 5/3 (LeGall 5/3) lifting wavelet in an FPGA so that I can do some image processing. Reading through some papers I have found the algorithm to code but I would like to perform the same thing in Matlab so that I can check my results. Can someone who knows about the wavelet toolbox tell... 13 Aug 2010 14:39

Noise estimation Hello, Is there a method to estimate the statistical properties of additive noise from a received signal observation. Assume we have y(k) = x(k) + n(k) and we observe the received signal y(k). I would like to know if there is a way to determine the autocorrelation of the noise process n(k), that is Rnn. ... 12 Aug 2010 18:04

frequency independent antennas.... Hello Forum, a common wire antenna works the best when its size is equal to half the incident radiation wavelength. That means that the physical size is a constraint in terms of the operating bandwidth and performance. There are frequency independent antennas that have a finite size but can work on a much large... 12 Aug 2010 14:45
FFT Windowing and Transmit Pulse Shaping So I'm pretty confused about something.While studying DFT windowing, I saw how rectangular window has lowest bandwidth compared to Hanning window( which is basically raised cosine), but higher side-lobes. But in all pulse shaping filter tutorials, apart from minimizing ISI they describe how the bandwidth of the rec... 12 Aug 2010 22:26
Polynomial used to create Galois field for AES? * Jaco Versfeld (jaco.versfeld (a)gmail.com) [100429 06:56]: Hi There, (My apologies for cross-posting) The following polynomial is used to create a "Galois field" GF(2^8) which is specified in the Advanced Encryption Standard (AES): p(x) = x^8 + x^4 + x^3 + x + 1. However, I checked the poly...

DSSS-CDMA query Dear All, I am trying to brush up my communication theory fundamentals. I have simple(perhaps foolish!) question on intutive understanding of CDMA. Shannon says that the capacity of a channel is directly proportional to bandwidth of signal. In other others for a given SNR if increasing B would give me more capac... 11 Aug 2010 15:49
how to minimize ringing Hello, I am trying to restore a one dimentional signal using wiener deconvolution with a PSF. Because it's important for me to restore sharpness, but more important, the shape at the transient edges- the ringing is getting in my way. I understand that ringing to some extent is unavoidable, but how can I miminize it... 10 Aug 2010 16:54

Calculate FFT in blocks and then average it. Hi guys, I have a very basic problem. I am able to calculate FFT of an input vector. But now what i want is, to subdivide the input vector into blocks, each having equal number of elements. An FFT needs to be performed on each individual block. The results of these FFTs are then averaged to give the final resu... 10 Aug 2010 19:06
