WebYou might have expect to see Zadoff-Chu sequence but this does not look like a Zadoff-Chu sequence. The Zadoff-Chu sequence for PRACH is in Frequency Domain, but this is the time domain sequence. The PRACH Zadoff-Chu is transformed to the time domain sequence as shown below via a transformation that is shown in How to Generate RACH … WebZadoff-Chu sequences are good candidates as they exhibit constant power in time and frequency. However the number of Zadoff-Chu sequences is limited which makes them unsuitable for use on their own. The generation and mapping of the SRS are discussed further in this section. Base sequence
