What is the difference between ratio estimation and regression estimation?
diferece between ratio and regression
What is the definition of front end estimation?
When using front-end estimation, we add or subtract the front digits, and then adjust for a more accurate estimation by estimating the sum of the digits to the right of the decimal point.
Useful when exact data is not required?
Estimation
Where can I get estimation worksheets ?
It is very easy to find high quality rounding and estimation worksheets for kids on the website WWW.estimation.com , this website also features a "grade" (or "class") filter , which allows more precise results. Also WWW.mathworksheets4kids.com has a wide range of estimation sheets available.
How is estimation different from guessing?
Estimation is making a rough guess to the approximate answer but it does'nt have to be exact. Guessing is giving random answers without thinking whether it's approximate or not.
What is channel estimation?
A person who is blind does channel estimation.
What is blind channel estimation?

What is SISO-OFDM?
SISO-OFDM is an OFDM system with one transmit and one receive antenna.
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.
What is 'ofdm'?
Orthogonal frequency-division multiplexing
What has the author R Harun written?

Can you do successive interference cancellation SIC in OFDM?
yes
What is meant by the term OFDM?
OFDM means Orthogonal frequency-division multiplexing. This is a method on encoding data which in digital television and radio. It is also used on 4G networks.
