Add Cyclic Prefix (Transmitter) (MATLAB) (m34138)
Keywords: CYCLIC, ECE, Guard, INTERVAL, OFDM, PREFIX, SDR, UIUC
Summary: This performs the simple but crucial task of adding the cyclic prefix for the transmission guard interval. This will protect real systems against multipath fading. NOTE: The MATLAB library was used in the initial version of the design but has since been replaced by an updated LabVIEW module. Please see ... current version.

Bits-to-Words (Transmitter) (LabVIEW) (m34120)
Keywords: BITS, ECE, LabVIEW, OFDM, SDR, UIUC, WORD
Summary: This is a seemingly trivial sub-VI that converts a parallel stream of bits to a parallel group of bit-words. While it could easily be done without a sub-VI, it's always important to practice modularity and simplicity for readability in the overall design. This makes the debugging ... the future.

Bits-to-Words (Transmitter) (MATLAB) (m34139)
Keywords: BITS, ECE, MATLAB, OFDM, TRANSMITTER, UIUC, WORDS
Summary: The fairly trivial operation of converting a set of bits to a set of words. NOTE: The MATLAB library was used in the initial version of the design but has since been replaced by an updated LabVIEW module. Please see the LabVIEW portion of the transmitter for the most current version.

FFT-to-Symbols (Receiver) (MATLAB) (m33849)
Keywords: FFT, MATLAB, Receiver, Spectrum, Symbols
Summary: The incoming OFDM symbol was generated by essentially performing a parallel to serial transformation via an Inverse Fourier Transform (IFT). This is frequently done in the digital domain by using the Inverse Fast Fourier Transform (FFT) algorithm. Thus, we wish to recover our spectrum where the bits were present in ... current version.

Frequency Synchronization (Receiver) (MATLAB) (m33848)
Keywords: Frequency, Offset, Phase, Recovery, Symbol, Synchronization, Training
Summary: When an OFDM symbol is received, there is almost a guarantee the mixing frequency will be out of phase and slightly different than the carrier frequency. This algorithm is designed to eliminate this inconsistency by way of a predetermined training symbol. This module code will soon be supplanted by a ... current version.

OFDM Symbol Decoder (Receiver) (MATLAB) (m33852)
Keywords: Final, MATLAB, Product, Receiver
Summary: This file brings together all of the previous files into one MATLAB interface. With one command, and the right parameters, one can successfully receive one training symbol and one data symbol. NOTE: The MATLAB library was used in the initial version of the design but has since been replaced by ... current version.
