What is OFDM training symbol?
Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital. Pilot signals and training symbols (preambles) may also be used for time.

2.4GHz is used & OFDM
What are the methods of isi mitigation?
The methods of ISI mitigation are 1- Adaptive Equalization 2- DS-Spread Spectrum 3- OFDM 4- Directional Antennas Hope this helps you. Regards Fahad
What is binary code languagethe-program-generated-by-the-compiler-after-translation-is-called?
Binary code is a system of representing data using two symbols, typically 0 and 1, which corresponds to the on and off states of a computer's electrical signals. The program generated by the compiler after translation is called "machine code" or "object code." This machine code is what the computer's processor can execute directly, as it is tailored to the specific architecture of the machine.

What is SISO-OFDM?
SISO-OFDM is an OFDM system with one transmit and one receive antenna.
Signals generated by the nervous system are called?
Nerve impulses.
How ofdm eliminates multipath effects?
Because OFDM systems use orthogonal frequency(carrier),at the receiver the others copies from multipath has a different phases from the direct one, and by multiplying the generated carrier in the receiver with all received signal and integrated it over [-pi,+pi] only one the direct signal have (1) at the output and the others have(0) output.
How many sub channels does OFDM use for carrying data?
OFDM uses 48 subchannels for data and 4 are used as Pilot Carriers.

What is loss of orthogonality means in OFDM technology?
In OFDM, sub-carrier spacing is maintained in such a way that the maximum of one sub-carrier occurs at the minimum of the successive sub-carrier, a loss of orthogonality results if this pattern is not achieved in the sub-carriers of OFDM transmission. Loss of orthogonality is due to ISI, ICS, Frequency offset amongst the sub-carriers of OFDM.
How you eliminate inter symbol interference in ofdm?
Inter symbol interference (ISI) in OFDM systems can be minimized by using a cyclic prefix. This involves adding a copy of the end of each OFDM symbol to the beginning before transmission. The cyclic prefix helps to mitigate the effects of multipath fading and reduces ISI by allowing the receiver to separate the OFDM symbols with a guard interval.
