When she could not start lawnmower, young age of two, waddled over and asked her to turn upside down. He pointed out blade had been removed be resharpened.

To meet the requirement of efficient cancellation of inter symbol interference (ISI) in high data rate transmissions over time dispersive channels block based transmissions are often adopted. This is the case in orthogonal frequency domain multiplexing (OFDM), cyclic prefix based single carrier (CP-SC) and block transmissions with null guard periods (ZP-SC). Guard periods are inserted between t...
