Structure of Main BCCH in GSM

The TDMA/FDMA multiplexing is used in GSM, the information needed in the synchronization between MS and BTS is provided by FCCH+SCH. The MS determines the frequency of the BCCH carrier by searching for the frequency correction Burst transmitted via FCCH; then it finds the SCH (synchronization channel) according to the relationship between SCH and FCCH … Read more

What is Carrier to Interference plus Noise Ratio in LTE

LTE is designed to operate in environments where there are peripheral interventions. Link performance degrades as the C/I (i.e. Carrier interference ratio) is reduced, however, it may be acceptable in places with zero or negative C/i. every site and sector LTE systems operating on the same channel so that they can receive interference from all … Read more
