5G Base Station: QAM Modulator and Demodulator

INGLEWOOD, Calif. - March 1, 2022 - PRLog -- QAM Modulator and Demodulator combine two amplitude modulation signals into a single data transfer channel is the technique of modifying any one characteristic (amplitude, frequency, or phase) of a relatively high-frequency carrier signal in proportion to the instantaneous value of the modulating signal or message signal is known as modulation. For example, the input data signals I and Q are amplitude modulated by sine and cosine carrier waves, respectively. The two modulated signals are merged and then processed in accordance with RF specifications. These signals are then frequency-converted and amplification is performed to satisfy the final frequency and amplitude criteria.

In contrast, in demodulation, signals from the transmitter enter the demodulator and are divided into two signals that are sent into separate mixers. The local oscillator generates needed frequency demodulation signals, which are in-phase and quadrature signals.

QAM is a modulation technology that combines two amplitude modulated signals into a single channel, thus doubling a system's bandwidth. QAM is also known as quadrature carrier multiplexing since the two signals are modulated and broadcast to the receiver at the same time.

Advantages of QAM

• Quadrature amplitude modulation Aside from increased channel capacity, QAM has various other advantages, which are stated below.
• One of the most significant advantages of QAM is its ability to sustain a high data rate. As a result, the carrier signal can carry a certain amount of bits. Because of these benefits, it is preferred in wireless communication networks.
• The noise immunity of QAM is quite strong. Noise interference is quite low as a result of this.
• It has a low mistake probability value.
• QAM makes excellent utilization of channel capacity. The carrier signal may transport more bits, resulting in a high data rate.
• Because of the high noise immunity, there is less noise interference during data transmission.
• The likelihood of incorrect values is negligible.
