Frequency Division Multiple Access Question and Answers

June 23, 2022 By WatElectronics

This article lists 50 Frequency Division Multiple Access MCQs for engineering students. All the Frequency Division Multiple Access Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Frequency Division Multiple Access.

FDMA refers to Frequency division multiple access, which is a channel access technique used in multiple access protocols. FDMA is different from Frequency division duplexing(FDD). Duplexing is shared between uplink and downlink transmissions.

In FDMA, each user shares the same frequency channel, each user transmits at a single frequency. The channel access technique takes place in the data link layer. It can use both analog and digital signals. The data transfer mode is continuous.

Compared with TDMA and CDMA, FDMA requires high-performance filters. FDMA is the division of frequency bands allocated for communication channels. In FDMA, Synchronization is not necessary.

For reducing crosstalk between the channels guard bands are required between adjacent signals. Cost is less due to design complexity being low. Mostly widely used in Mobile communications, Telecommunications, GSM,2G, TACS, and also bit rate increases.
