OFDM in its primary form is considered as a digital modulation technique , and not a multi-user channel access method, since it is used for transferring one bit stream over one communication channel using one sequence of OFDM symbols.
Read moreWhy we use digital modulation techniques?
Digital Modulation provides more information capacity, high data security, quicker system availability with great quality communication . Hence, digital modulation techniques have a greater demand, for their capacity to convey larger amounts of data than analog modulation techniques.
Read moreWhat are the different digital modulation techniques used in mobile communication?
Digital Modulation can further be classified into four types:
Read moreWhat is digital modulation and its types?
There are three types of digital modulation, and they are: Amplitude shift key (ASK) Frequency shift key (FSK) Phase shift key (PSK)
Read moreWhich digital modulation technique is best?
Frequency modulation is more effective in terms of noise tolerance and more suited for data transmission than AM. Phase modulation is more complex and costly but is relatively immune to noise and theoretically makes the best use of bandwidth for a given transmission rate.
