Dipole antenna — A schematic of a half wave dipole antenna connected to an unbalanced coaxial cable. Better practice is to connect the balanced dipole to the unbalanced line with a balun. A dipole antenna is a radio antenna that can be made of a simple wire, with … Wikipedia
Metamaterial antenna — This Z antenna tested at the National Institute of Standards and Technology is smaller than a standard antenna with comparable properties. Its high efficiency is derived from the Z element inside the square that acts as a metamaterial, greatly… … Wikipedia
Space–time block code — This article deals with coherent space–time block codes (STBCs). For differential space–time block codes, see differential space–time codes.Space–time block coding is a technique used in wireless communications to transmit multiple copies of a… … Wikipedia
Pulse-amplitude modulation — Principle of PAM: (1) original signal, (2) PAM signal, (a) amplitude of signal, (b) time Pulse amplitude modulation, acronym PAM, is a form of signal modulation where the message information is encoded in the amplitude of a series of signal… … Wikipedia
Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… … 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
Ultra-wideband — (aka UWB, ultra wide band, ultraband, etc.) is a radio technology that can be used at very low energy levels for short range high bandwidth communications by using a large portion of the radio spectrum. UWB has traditional applications in non… … Wikipedia
Noncoherent STC — Non coherent space time codes are a way of transmitting data in wireless communications. In this multiple antenna scheme, it is assumed that the receiver only has knowledge of the statistics of channel. Non coherent space time transmission… … Wikipedia
