Normal Burst for GMSK



The time interval of a TS corresponds to 156.25 bits.






Normal Burst
for GMSK: 114 bits of useful information
  • Used to carry Traffic or control information
  • Tail bits are sequence of zero bits to indicate the start and the end of burst
  • Data bits carries Traffic or control information
  • Training bits carries a training sequence used by adaptive equalizer to estimate the channel
  • Flag bit indicates type of information being transmitted (User info/signaling info (TCH or FACCH)
  • Guard bits are used to avoid overlapping between adjacent timeslots
