2. One Preamble Option e.g. 16MHz Average PRF

One Preamble Option e.g. 16MHz Average PRF
Preamble
Data
Peak Preamble PRF = ~ 31 MHz
(actually 494/16)
Peak Preamble PRF = 494 MHz
Average Data PRF
~ 16 MHz
1uS => 16 pulses
Average Preamble PRF
~ 16 MHz ( actually 494/31)
=> every 1uS, 16 pulses
This maintains same pulse amplitude for Preamble and Data

3. Resultant Burst Length (~16MHz PRF average)

Resultant Burst Length (~16MHz PRF average)
The longer the burst, the more noise a non-coherent receiver must “let in”.
Note: The above is an excel spreadsheet so you can play around with the numbers

Resultant Burst Length (~4MHz PRF average)
The longer the burst, the more noise a non-coherent receiver must “let in”.
