- This simulation plots the Effective SNR of and OFDM as a function of Output Power Backoff from 0 to 9.5 dB, for three different number of carriers.
windowing
- This simulation shows the effective SNR verse subcarrier number as a result of band pass filtering of the signal

- when SNR is high , 1st sample estimator provides good estimate of A. it has no ise effect . so we don’t need averaging effect to reduce noise when SNR is high. However variance is still low in sample mean estimator which shows that in reality ,samp

- A random stream of bits the size of the desired transport block undergoes Downlink Shared Channel (DL-SCH) coding to rate match the transport block to the available PDSCH bits. Scrambling, modulation, precoding and layer mapping are then app
