Channel state information — In wireless communications, channel state information (CSI) refers to known channel properties of a communication link. This information describes how a signal propagates from the transmitter to the receiver and represents the combined effect of … Wikipedia
Fading — This article is about signal loss in telecommunications. For the poetry book, see Fading (book). For other uses, see Fade (disambiguation). Frequency selective time varying fading causes a cloudy pattern to appear on a spectrogram. Time is shown… … Wikipedia

Single-frequency network — For other uses, see SFN (disambiguation). A single frequency network or SFN is a broadcast network where several transmitters simultaneously send the same signal over the same frequency channel. Contents 1 Overview 2 OFDM and COFDM 3 DVB T SFN … 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
Pulse-position modulation — is a form of signal modulation in which M message bits are encoded by transmitting asingle pulse in one of 2^M possible time shifts. This is repeated every T seconds, such thatthe transmitted bit rate is M/T bits per second. It is primarily… … Wikipedia
Narrowband — In radio, narrowband describes a channel in which the bandwidth of the message does not significantly exceed the channel s coherence bandwidth. It is a common misconception that narrowband refers to a channel which occupies only a small amount of … 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
Space–time code — A space ndash;time code (STC) is a method employed to improve the reliability of data transmission in wireless communication systems using multiple transmit antennas. STCs rely on transmitting multiple, redundant copies of a data stream to the… … Wikipedia
