diferece between ratio and regression
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.
Estimation
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.
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.

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

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