OFDM System Implementation in DSP Platform TMS320C6678

OFDM System Implementation in DSP Platform TMS320C6678

The Orthogonal Frequency Division Multiplexing (OFDM) system is already used in commercial applications and is capable to deal with Intersymbolic Interference (ISI) caused by multipath channels. This system gained popularity after the application of the Fast Fourier Transform (FFT) and its inverse (IFFT) to modulate the signal in many subcarriers. This paper discusses implementation aspects of ...

Synthetic Aperture Radar Implementation on a TMS320C6678 Multicore DSP

Real Time Implementation of OFDM system on DSP Processor

Orthogonal Frequency Division Multiplexing (OFDM) technology has been adopted by a variety of standards. This technology was chosen due to its robustness at high data rates in a frequency selective multipath channel. This paper describes a real-time implementation of a half-duplex OFDM system using Matlab software simulink, DSP processor TMS320C6713 and Code Composer Studio. In this approach, M...

DSP based receiver implementation for OFDM acoustic modems

Significant progress has been made recently on the use of multicarrier modulation in the form of orthogonal frequency division multiplexing (OFDM) for high data rate underwater acoustic communications. In this paper, we present implementation results of OFDM acoustic modems under different settings with either one or two parallel data streams transmitted, whose data rate is 3.2 KB/s or 6.4 KB/s...

CO-OFDM DSP Channel Estimation

This paper solves the Non Linear Schrodinger Equation using the Split Step Fourier method for modeling an optical fiber. The model generates a complex wave of optical pulses and using the results obtained two graphs namely Loss versus Wavelength and Dispersion versus Wavelength are generated. Taking Chromatic Dispersion and Polarization Mode Dispersion losses into account, the graphs generated ...
