Block Transceivers of DM and Beyond

Simple transceivers or block transceivers can be found in a variety of applications. The demand for data traffic has increased the need for mobile communication and subsequently, the need for block transceivers. Simple transceivers are commonly yielded in applications where orthogonal frequency-division multiplexing (OFDM) is used because it increases spectral efficiency. Here’s what you need to know about simple transceivers or block transceivers.

Block Transceivers of DM and BeyondBenefits of Simple Transceivers
Transceivers have memory that make it possible to eliminate redundancy or render redundancy as low as a single symbol per block. This is possible regardless of the size of the channel memory. Multi-carrier modulation (MCM) schemes would be proven to be more efficient when there are channels with frequency selective behavior. The most popular MCM method will increase spectral efficiency through the use of simple block transceivers.

OFDM systems have half the amount of redundancy, but they manage to keep the computational complexity comparable. This is made possible by linear time-invariant transceivers that are also memoryless. Because of their ability to offer reduced redundancy, they require the use of fast algorithms and low-complexity arithmetical operations.

Uses for Simple Transceivers
Simple transceivers are most often used in mobile communications. Mobile handsets require transceivers to convert the signal to useable forms that allow communication to occur on a continual basis. Many designers look to these types of transceivers to complete their designs.

A typical amateur radio transceiver will come equipped with a 120VAC/240 VAC built-in power supply with 100 or more watts of output. The transceiver may have dual receivers, roofing filters, and dual notch filters. These types of transceivers may also feature a 32-bit floating point DSP filter and three-band parametric microphone equalizer. A built-in automatic antenna tuner may also be included with front panel controls. Adjustable noise blankers, transmit bandwidth, and noise reduction are just some of the features that designers can expect from this type of transceiver.

There are numerous uses for simple transceivers that are simply not apparent by many users. Ham radio is one of the most common uses, but there are numerous other uses as well. Consider how transceivers can be used in your application and purchase the one that best suits your needs.

Cost of Simple Block Transceivers
The cost of simple block transceivers ranges from as low as $200 up to $1500 or more. The price, typically, depends upon the range required and the use of the application. Every designer is likely to find simple block transceivers to meet their project’s budget.

The Many Uses of Block Transceivers
If a block transceiver is needed for a project, there are plenty online at electronics stores. Designers have the flexibility of finding the best product for them. Whether they are being used for mobile applications or amateur radio, the simple block transceiver is affordable, versatile, and able to fit a designer’s needs. Contact an expert if questions arise about the specifications of the product. They’ll be a good source of information to help designers find the best device for your project.
