In telecommunications, diversity reception refers to a method for improving reception of a transmitted signal, by receiving and processing multiple versions of the same transmitted signal. The way in which those multiple versions of the signal are received, characterizes the diversity technique: Telecommunication is the extension of communication over a distance. ... Signaling, or signal, may mean: Look up signal in Wiktionary, the free dictionary. ...
space diversity: receiving multiple versions of the transmitted signal, that have followed a different propagation path. In the case of wired transmission, this can be achieved by transmitting via multiple wires. In the case of wireless transmission, this can be achieved by transmitting to multiple receiving antennas (antenna diversity).
polarisation diversity: receiving multiple versions of a wirelessly transmitted signal via antennas with different polarisation.
time diversity: receiving multiple versions of the same signal, being transmitted at different time instances
frequency diversity: receiving multiple versions of the same signal, being transmitted at different carrier frequencies.
After receiving the multiple versions of the signal, a diversity combining technique is applied before further signal processing takes place. Antenna Diversity is a transmission technique in which the information-carrying signal is transmitted along different propagation paths. ... Diversity Combining is the technique applied to combine the multiple received signals of a diversity reception device into a single improved signal. ...
Another name for a diversity receiver is rake receiver. A rake receiver is a radio receiver designed to counter the effects of multipath fading. ...
Diversityreception refers to a technique of monitoring multiple frequencies from the same signal source, or multiple radios and antennas monitoring the same frequency, in order to combat signal fade and interference (see also Antenna diversity).
The "business case for diversity", as it is often phrased, is that in a global and diverse marketplace, a company whose makeup mirrors the makeup of the marketplace it serves is better equipped to thrive in that marketplace than a company whose makeup is homogenous.
Business diversity consultants and diversity trainers often treat the social consequences of diversity as secondary; their primary focus is to enable the company to function in a heterogeneous or global economy.
In electronics, diversityreception refers to a method for improving reception of a radio signal, typically achieved by the use of dual receivers whose antennas are located in physically distinct locations (which can be less than a metre apart).
The best-known practical application of diversityreception is in wireless microphones, and in similar apparatuses such as wireless guitar systems.
A wireless microphone or sound system using diversityreception will switch to the other antenna within microseconds if one antenna experiences noise, providing an improved quality signal with fewer drop-outs and noise.
