Demodulate using OFDM method - MATLAB
Documentation Help Center Documentation. The OFDMModulator object modulates a signal using the orthogonal frequency division modulation method. The output is a baseband representation of the modulated signal. Enclose each property name in quotes. For example, comm. Unless otherwise indicated, properties are nontunable , which means you cannot change their values after calling the object. Objects lock when you call them, and the release function unlocks them.
Orthogonal frequency-division multiplexing
Many of the present communication systems tend to use Orthogonal Frequency Division Multiplexing OFDM because of the higher data rates, low inter symbol interference ISI and easily compatible to the variation in the frequency. Field Programmable Gate Arrays provide the better platform for the variation of data rates and moreover they are of low cost, easily programmable. Authors are requested to submit articles directly to Online Manuscript Submission System of respective journal. Related article at Pubmed , Scholar Google. In some applications, it is desirable to transmit the same information-bearing signal over several channels.
In telecommunications , orthogonal frequency-division multiplexing OFDM is a type of digital transmission and a method of encoding digital data on multiple carrier frequencies. Chang of Bell Labs in OFDM was improved by Weinstein and Ebert in with the introduction of a guard interval , providing better orthogonality in transmission channels affected by multipath propagation. This maintains total data rates similar to conventional single-carrier modulation schemes in the same bandwidth.
