Introduction to Communication systems Chapter 5-Multiplexing (original) (raw)

AI-generated Abstract

Multiplexing enables the simultaneous transmission of multiple signals over a single communication channel, enhancing the efficiency and capacity of communication systems. There are two primary types of multiplexing: Frequency Division Multiplexing (FDM) and Time Division Multiplexing (TDM). FDM is primarily used for analog signals, where individual signals are assigned distinct frequencies within a common bandwidth, while TDM interleaves signals in time, allowing them to utilize the entire bandwidth for short intervals. Additionally, Space-Division Multiplexing (SDM) is introduced, utilizing directionality to further optimize channelization, particularly in wireless communications.
