FFTToy (exe)

FFTToy was developed to enable practitioners to quickly examine and filter signals. In addition, with FFTToy you can simply generate artificial vectors comprised of sine waves and then use those vectors to test your FFT filter. The tool computes a multiplication in the Fourier domain using the FFT coefficient vector...

Multi-Level Weighted Combining of Retransmitted Vectors in Wireless Transmissions

This paper proposes weighted combining of retransmitted vectors in wireless transmissions for improved data recovery in single and multiple-antenna wireless LAN transceivers. Combining is suggested at multiple-levels in the receiver design at the post-equalizer, post-demapper and post-decoder stages. The best achievable performance is obtained by exploiting diversity in time, equivalent...

Interpolation Based Transmit Beamforming for MIMO-OFDM With Limited Feedback

Transmit beamforming and receive combining are simple methods for exploiting spatial diversity in Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system. Optimal beamforming requires channel state information in the form of the beamforming vectors for each OFDM subcarrier. This paper proposes to a limited feedback architecture that combines beamforming vector...

Vector Cross Product Program (zip)

This allows you to cross two 3D vectors. Tips- if you get [0,0,0], then the two 3D vectors are perpendicular!! Crossing two 3D vectors give you the vector mutually perpendicular to these two vectors. This program is like the program obtainable on the graphical calculator, but this one's for the...

Spherical Linear Interpolation for Transmit Beamforming in MIMO-OFDM Systems With Limited Feedback

Transmit beamforming and receive combining can be simply implemented over frequency selective channels by using Multiple-Input Multiple-Output MIMO technology combined with Orthogonal Frequency Division Multiplexing OFDM in what is known as MIMO-OFDM. Generally this requires knowledge of the transmit beamforming vectors for every tone at the transmitter. In systems without...
