Diversity Coding — is a particular technique for antenna diversity and is implemented by space time coding … Wikipedia
Coding theory — is the study of the properties of codes and their fitness for a specific application. Codes are used for data compression, cryptography, error correction and more recently also for network coding. Codes are studied by various scientific… … 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 index — A diversity index is a statistic which is intended to measure the local members of a set consisting of various types of objects. Diversity indices can be used in many fields of study to assess the diversity of any population in which each member… … 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
Space-time block coding based transmit diversity — (STTD) is a method of transmit diversity used in UMTS third generation cellular systems. STTD is optional in the UTRAN air interface but mandatory for user equipment (UE). STTD utilizes space time block code (STBC) in order to exploit redundancy… … 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
Dirty paper coding — In telecommunications, dirty paper coding (DPC) is a technique for efficient transmission of digital data through a channel subjected to some interference known to the transmitter. The technique consists of precoding the data in order to cancel… … Wikipedia
Transmit diversity — is radio communication using signals that originate from two or more independent sources that have been modulated with identical information bearing signals and that may vary in their transmission characteristics at any given instant. It can help … Wikipedia
MIMO — This article is about MIMO in wireless communication. For other uses, see MIMO (disambiguation). Understanding of SISO, SIMO, MISO and MIMO (note that the terms input and output refer to the radio channel carrying the signal, not to the devices… … Wikipedia
