A transceiver consists of a receiver and a transmitter. The architecture and key characteristics of different types of receivers and transmitters are covered in this chapter, helping the designer to choose the optimum for a specific application.
The main function of a receiver is the demodulation of a wanted signal in the presence of undesired interferers and noise. Due to the strong attenuation during air transmission, the RF signal has to be amplified and recovered. Taking into account scenarios with varying attenuation, a wide dynamic range is required for the detection of signals with high data-rates.
A hardware efficient 64-QAM low- IF transceiver baseband for broadband communications
Fig. 1 shows a typical functional block diagram of QAM transceiver for last-mile broadband digital communication systems, such as digital CATV [I], SCM-VDSL and Wireless MAN . The transmitter mainly consists of an FEC encoder, a symbol mapper, a Nyquist pulse
Implementation of a digital IF transceiver for SDR-based WiMAX Base Station
ABSTRACT This paper presents the implementation and performance of a Software Defined Radio (SDR) technology-based-Digital Intermediate Frequency ( IF ) transceiver for IEEE 802.16 d standard, often referred to as a WiMAX (Worldwide Interoperability for Microwave
FPGA implementation of an IF transceiver for OFDM-based WLAN
ABSTRACT This paper deals with the design and implementation on FPGA of an intermediate frequency transceiver for OFDM-based WLAN. The circuit has been particularized for Hiperlan 2 standard, but most of the work can be generalized to IEEE
