alam niyo kung sino man ang sumasagot katanungan na narito please stop kasi kami humihingi kami ng sagot yung tmang sagot sayang ang pera na aming ibinabayad so please stop.
Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital. Pilot signals and training symbols (preambles) may also be used for time.
Orthogonal frequency-division multiplexing
2.4GHz is used & OFDM
The methods of ISI mitigation are 1- Adaptive Equalization 2- DS-Spread Spectrum 3- OFDM 4- Directional Antennas Hope this helps you. Regards Fahad
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.

SISO-OFDM is an OFDM system with one transmit and one receive antenna.
Nerve impulses.
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.
OFDM uses 48 subchannels for data and 4 are used as Pilot Carriers.
Orthogonal frequency-division multiplexing
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.
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.
