Cyclic Prefix problem in LTE

The problem is fixed by adding a guard time between each symbol to avoid the ISI. The ISI is still present but is not disturbing for the receiver. Principle :…

What is Cyclic prefix in LTE ?

The guard period after each rectangular pulse carrying the modulated data symbol is a simple and efficient method to deal with multi-path reception. The cyclic prefix (CP) simply consists of…

How Normal and Extended Cyclic Prefix in LTE

The key to making OFDM realizable in practice is the use of the FFT algorithm, which has low complexity. In order for the IFFT/FFT to create an ISI-free channel, the…

How Frequency Band Selection and Cyclic Prefix Planning for LTE

It is very important when we talk about LTE Planning frequency band selection and Cyclic Prefix planning here I write basic background of it. Frequency Band Selection As many Operators…
