Freeware Listing: Matched Filter
- Match n Freq
- License: Freeware

Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency. Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay. Minimizing Intersymbol Interference in a read/write channel for disc drives by shaping and slimming an isolated readback pulse was the main objective for writing this program.

- implementation of digital pulse compression using matlab
- License: Freeware

In Radars, range resolution and long range of operation are the two important aspects. Long range operation means the maximum distance over which radar can detect the targets. The radar transmit modulated pulses to take the advantages of better processing gain and resolution of these waveforms are compared to continuous wave pulse. Radar Echo of these modulated signals are received, it has to be processed in filter matched to the modulating waveform to get the best SNR gain at the output. The matched filtering operation is done by Pulse compression filter. The matched filter is filter which gives best SNR (2E/N) by matching the transfer function of the filter with the time delayed version of the signal which is applied at the input of the filter.

- PERFORMANCE ANALYSIS OF SYMBOL/CHIP BASED MINIMUM
- License: Freeware

Current direct sequence code division multiple access (DS-CDMA) system suffer from Multiple access interference (MAI) and Inter symbol interference (ISI) due to the frequency selective channel. This interference can be avoided by use of Adaptive Beamforming. There are two different minimum variance Beamformer configurations for the base station receiver in direct sequence code division access (DS-CDMA) systems, namely a chip- based and a symbol-based configuration. In this paper chip- based and symbol- based configurations are studied. In symbol-based configuration, spatial diversity is exploited after despreading and interfering components are rejected, based on both their power and code correlation with the Signal of interest (SOI).
