What is the sub-carrier spacing in LTE OFDM? How many sub-carriers make Resource Block (RB)? What is the minimum and maximum number of RBs an LTE system can have? What bandwidths do these minimum and maximum RBs represent roughly?
What happen in the system when we play with the value of sub-carrier spacing ?
I know 15 Khz spacing is used between between two sub carrier. From where this 15 Khz is derived ? What things are considered to calculate this number ?
