It is not to be confused with Differential space–time code. Space–time block coding is a technique used in wireless communications to transmit multiple copies of a data stream across a number of antennas and to exploit the various received versions of the data to improve the reliability of data transfer. The fact that the transmitted signal ...
A space–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 receiver in the hope that at least some of them may survive the physical path between transmission and ...
utm_source Identifies which site sent the traffic, and is a required parameter. Source tells you the place that the ad was distributed : utm_source=google: utm_medium Identifies the channel that referred a user to your site: , such as Pay-per-click or email. utm_medium=ppc: utm_campaign Identifies a specific product promotion or strategic campaign.
The International Tunnelling and Underground Space Association (ITA-AITES) is a non-governmental, non-profit organization founded in 1974, [1] comprising currently 78 member nations [2] and 266 corporate or individual affiliate members, [3] aiming to encourage the use of the subsurface for the benefit of public, environment and sustainable ...
Space–time trellis codes ( STTCs) are a type of space–time code used in multiple-antenna wireless communications. This scheme transmits multiple, redundant copies of a generalised TCM signal distributed over time and a number of antennas ('space'). These multiple, 'diverse' copies of the data are used by the receiver to attempt to ...
Space traffic management is defined by the International Academy of Astronautics (IAA) as "the set of technical and regulatory provisions for promoting safe access into outer space, operations in outer space and return from outer space to Earth free from physical or radio-frequency interference ."
