M-ary Encoding
It Involves transmitting of more than two bits simultaneously on the same signal that can help to save bandwidth by efficiently utilizing the available frequency spectrum.
- M-ary ASK (Amplitude Shift Keying):It is also known as M-ASK or M-FSK,In this multiple amplitude levels are used to represent several different combinations of bits.Each amplitude level represents a specific pattern of bits which allows transmission of multiple bits in each signaling interval.
- M-ary FSK (Frequency Shift Keying):In this the carrier frequency is shifted to represent different symbols.It is Similar to M-ary ASK as it allows transmission of multiple bits per symbol by using multiple frequency shifts.
- M-ary PSK (Phase Shift Keying):It involves shifting the phase of the carrier wave to represent different symbols.By changing the phase of the carrier wave multiple symbols can be represented each corresponding to a unique bit pattern.
Digital Modulation Techniques
Modulation is the Fundamental Process in Communication Systems, In Modulation Low-Frequency Message Signal Blends with High-Frequency Carrier Frequency to Enable Efficient Transfer of the Signal.
