Diversity combining — is the technique applied to combine the multiple received signals of a diversity reception device into a single improved signal. Contents 1 Various techniques 2 Switched combining two way radio example 2.1 How signals are evaluated … Wikipedia
Combining — may refer to: Combining capacity, in chemistry Combining character, in digital photography Combining form, in linguistics Combining grapheme joiner, Unicode character that has no visible glyph Combining Cyrillic Hundred Thousands, modifier in the … Wikipedia
Diversity scheme — Terrestrial microwave radio system with two antenna arrays configured for space diversity In telecommunications, a diversity scheme refers to a method for improving the reliability of a message signal by using two or more communication channels… … Wikipedia
Diversity gain — In wireless communications, diversity gain is the increase in signal to interference ratio due to some diversity scheme, or how much the transmission power can be reduced when a diversity scheme is introduced, without a performance loss.… … Wikipedia
Antenna diversity — Antenna diversity, also known as space diversity, is one in a superset of wireless diversity schemes that utilizes two or more antennas to improve the quality and reliability of a wireless link. Often, especially in urban and indoor environments … Wikipedia
Cooperative diversity — is a cooperative multiple antenna technique for improving or maximising total network channel capacities for any given set of bandwidths which exploits user diversity by decoding the combined signal of the relayed signal and the direct signal in… … Wikipedia
Maximal-ratio combining — In telecommunications, maximal ratio combining is a method of diversity combining in which: (a) the signals from each channel are added together, (b) the gain of each channel is made proportional to the rms signal level and inversely proportional … Wikipedia
Site diversity — is a technique to limit the effect of rain fade in satellite communications, mainly in the Ka band. The downlink transmissions ofsatellites cover very large areas, that will have different weather. The sitediversity technique consists of linking… … Wikipedia
Crop diversity — is the variance in genetic and phenotypic characteristics of plants used in agriculture. Crops may vary in seed size, branching pattern, in height, flower color, fruiting time, or flavor. They may also vary in less obvious characteristics such as … Wikipedia
Macrodiversity — In wireless communication, Macrodiversity means a situation where several receiver antennas and/or transmitter antennas are used for transferring the same signal. The distance between the transmitters is much longer than the wavelength. In a… … Wikipedia
Radio repeater — A radio repeater is a combination of a radio receiver and a radio transmitter that receives a weak or low level signal and retransmits it at a higher level or higher power, so that the signal can cover longer distances without degradation. This… … Wikipedia
