    Hello Orthogonal
Click For Summary
SUMMARY

The discussion centers on the concept of "bursty nature" in telephony, particularly in the context of Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), and Frequency Division Multiple Access (FDMA) systems. Participants confirm that bursty nature refers to periods of high transmission activity, such as numerous phone calls, contrasted with times of low activity, leading to underutilization of allocated resources like orthogonal codes and timeslots. The analogy of a CD/DVD with a radial scratch illustrates how bursty noise affects data transmission, highlighting the importance of error correction techniques like Reed-Solomon coding to manage such noise.

hello

From wiki..
''There are a fixed number of orthogonal codes, timeslots or frequency bands that can be allocated for CDM (Sync CDMA), TDMA, and FDMA systems, which remain underutilized (to fail to utilize fully) due to the bursty nature of telephony and packetized data transmissions. ''

My question is what does the bursty nature of telephony mean actually? So far I understnad - bursty nature means sometime very high number of transmission (i.e. phone calls) while other time it might be very low number of transmission? And when the number of calls are very low, the codes/time slots/ frequency bands are unused, hence underutilized.

Is it right what I understand?

Thanks

The typical example is a CD/DVD with a radial scratch. The damage done (noise created) is "bursty" because it is constrained to a cluster in time/space. This is why Reed-Solomon is used for error correction - it's good for bursty noise.
