WebDec 2, 2014 · In regard to TDMA and digital technology, the 12.5 kHz channel bandwidth is maintained. The RF spectrum efficiency is achieved when two voice channels share time … WebThe GSM standard [ 1] specifies a TDMA frame as a combination of 8 time slots. Each time slot has a duration of 3/5200 seconds (about 0.577 ms) and a time slot number (TN) from 0 to 7. GSM frames use GMSK modulation, where one symbol is equivalent to one bit. Each time slot is 156.25 bits long. The content of a time slot is called a burst.

WebFrequency-division multiple access ( FDMA) is a channel access method used in some multiple-access protocols. FDMA allows multiple users to send data through a single communication channel, such as a coaxial cable or microwave beam, by dividing the bandwidth of the channel into separate non-overlapping frequency sub-channels and … WebCode-division multiple access ( CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel.
