burst

  1. In general, a burst is understood to be an irregularly occurring accumulation of data (data clumps) or an oscillation surge that is not evenly distributed over time. Burst traffic is understood to be data transmission with bursts of data
  2. In memory technology, it is a fast technique for data transfer in which a block of data is automatically generated as a series of consecutive addresses whenever the processor requests a single address. The assumption is that the following address requested by the processor follows the previous one. This mode can be used for both the write operation and the read operation.
  3. In color television, the burst forms the color reference signal for the frequency and phase of the color carrier. It is a burst of 11 oscillations of the color subcarrier frequency transmitted on the rear black shoulder in the horizontal blanking interval.
  4. In mobile radio transmission, one speaks of a burst in connection with a data packet that is transmitted from the terminal to the basestation. There are several different types of burst. 4a. The normal burst. It consists of 148 bits, namely 3 tail bits( TB), 58 information bits, 26 bits training sequence, another 58 information bits and 3 tail bits. The Normal Burst mode is used for normal communication between the terminal and the radio base station. 4b. The Access Burst. It consists of 87 bits, namely 7 tail bits, 41 bits training sequence, 36 information bits and another 3 tail bits. It is used only in the uplink in the Random Access Channel( RACH). 4c. The S-Burst. The synchronization burst differs from the normal burst in that it has a 64-bit training sequence. The number of information bits is correspondingly shorter. The S-burst is only transmitted in the downlink in the synchronization channel( SCH). 4d. The F burst. The Frequency Correction Burst consists of 0 bits only. The S-burst is detected and demodulated by the terminal. It is only transmitted in the downlink in the frequency correction channel( FCCH). 4e. The Fill-In Burst. It is used to fill time slots that must be filled, for example, to ensure transmission power.
