Quadrature Amplitude Modulation: Modulator and Demodulator

QAM Modulator and Demodulator combine two amplitude modulation signals into a single data transfer channel: 1.

Overview

QAM Modulator and Demodulator combine two amplitude modulation signals into a single data transfer channel:

1. 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.
2. 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.

Key features

  • 1. Quadrature amplitude modulation Aside from increased channel capacity, QAM has various other advantages, which are stated below.
  • 2. 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.
  • 3. The noise immunity of QAM is quite strong. Noise interference is a bit low as a result of this.
  • 4. It has a low mistake probability value.
  • 5. QAM makes excellent utilization of channel capacity.
  • 6. The carrier signal may transport more bits, resulting in a high data rate.
  • 7. Because of the high noise immunity, there is less noise interference during data transmission.
  • 8. The likelihood of incorrect values is negligible.

Benefits

  • 1. QAM is a modulation technology that combines two amplitude modulated signals into a single channel, thus doubling a system’s bandwidth.
  • 2. Digital analysis of QAM modulators utilizing “Verilog HDL” code and an “RTL compiler.”
  • 3. QAM is a modulation method that is used to send digital data between two places utilizing analog signals.
  • 4. Method of transmitting data and information via a carrier signal, such as an LTE waveform.
  • 5. There are 16-QAM, 64-QAM, and 256-QAM QAM schemes in both wireless and wireline communications, as well as even higher QAM schemes, such as 1024-QAM, which are presently being studied for the future growth of LTE/LTE-Advanced Pro and 5.

Three Major Inflection Points for Sourcing Bluetooth Intellectual Property

Synopsys is now shipping support for Bluetooth® 5.4, the latest specification from the Bluetooth SIG (Special Interest Group). The enhancements in Bluetooth 5.4 will open additional markets and use cases. This is one of the many inflection points in the Bluetooth Low Energy market that will be discussed in this paper.

Part 2: Opening the 5G Radio Interface

Carriers are now deploying 5G across the globe driven by the need to keep up with relentless mobile data growth. 5G New Radio (NR) operates at higher frequencies to increase bandwidth, but at the expense of range. There will therefore be a need for a much larger number of 5G RUs to provide the same coverage. The availability of cost-effective, reliable and open 5G radio units is therefore critical.

An Integrated, Tunable RF Filter: an Enabler for Reconfigurable Front-Ends

This paper presents the design and performance of a key RF circuit necessary for the realization of a reconfigurable, integrated RF front-end: a tunable frequency, selectable bandwidth, on-chip, “SAW replacement” filter. The on-die tunable filter presented here has a tunable center frequency up to 1 GHz, a selectable bandwidth up to 40 MHz, and an adjacent channel rejection down to 60 dB.

Design considerations for integrated CMOS receivers

To meet the demands for the multi-band, multi-mode wireless standards in the current market, a highly integrated wireless receiver (RX) is desired. CMOS technology has become the technology of choice for the integrated receiver design.

Silicon IP for Programmable Baseband Processing

An efficient IP reuse strategy relies on IP blocks with wide applicability. That makes generic blocks, such as programmable processors preferable. However, in many applications such as handheld wireless terminals, additional silicon area and power consumption compared to fixed function solutions can not be accepted.
