This file takes a patch antenna and a dipole, rotates the dipole, and calculates the overall output levels, taking into consideration the array pattern, and a variable combiner. There are extensive comments to show what was being attempted, and some commented out sections to show how the file was debugged and some variations of analysis that could be done.

DSP education is being challenged to move students beyond theory to DSP implementations. Dr. Mark A. Yoder, professor of electrical and computer engineering at Rose-Hulman Institute of Technology, addresses this need with multimedia signal processing labs in which students use Simulink and Real-Time Workshop to design and implement programs onto DSP chips that synthesize music in real time.

fSGolayFilt is a fast polynomial smoothing filter for uniformly spaced signals. This implementation offers less flexibility than other versions found in the MATLAB Central (eg. from Jianwen Luo, YangQuan Chen or Vassili Pastushenko), but it is optimized for speed by using a C-Mex function for the calculations.

PHPMQ is an Open Source serverless messaging toolkit for PHP, giving the PHP developer ability to perform JMS operations such as sending and receiving messages on queues and topics while ensuring delivery and enabling persistent messaging. Connecting PHP to a messaging bus is equivalent to connecting it to a database; the possibilities for using this infrastructure are endless, PHP developers using the PHPMQ will be able to communicate with other elements in the messaging bus, thus breaking the barrier between the two worlds.

Computes BER v EbNo curve for convolutional encoding / soft decision Viterbi decoding scheme assuming BPSK. Brute force Monte Carlo approach is unsatisfactory (takes too long) to find the BER curve. The computation uses a quasi-analytic (QA) technique that relies on the estimation (approximate one) of the information-bits Weight Enumerating Function (WEF) using a simulation of the convolutional encoder.
