Zadoff-chu sequence in 5g
  1. Why Zadoff Chu sequence?
  2. What is Zadoff Chu sequence in LTE?

Why Zadoff Chu sequence?

Zadoff–Chu sequences are an improvement over the Walsh–Hadamard codes used in UMTS because they result in a constant-amplitude output signal, reducing the cost and complexity of the radio's power amplifier.

What is Zadoff Chu sequence in LTE?

Zadoff Chu (ZC) sequences are the primary manifestation of spread spectrum in modern cellular systems including LTE and 5G NR, displacing PN and Walsh sequences which were the mainstays of 3G cellular (WCDMA and cdma2000) and IS-95.
