2. Space–time block code - Wikipedia

   en.wikipedia.org/wiki/Space–time_block_code

   Their original scheme was based on trellis codes but the simpler block codes were utilised by Siavash Alamouti, [6] and later Vahid Tarokh, Hamid Jafarkhani and Robert Calderbank [7] to develop space–time block-codes (STBCs). STC involves the transmission of multiple redundant copies of data to compensate for fading and thermal noise in the ...

3. Space–time code - Wikipedia

   en.wikipedia.org/wiki/Space–time_code

   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 ...

   en.wikipedia.org/wiki/StorageTek

   Storage Technology Corporation (StorageTek or STK, earlier STC) was a data storage technology company headquartered in Louisville, Colorado. [1] New products include data retention systems, which it calls "information lifecycle management" (ILM).

5. Space–time trellis code - Wikipedia

   en.wikipedia.org/wiki/Space–time_trellis_code

   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 ...

6. Space–time block coding based transmit diversity - Wikipedia

   en.wikipedia.org/wiki/Space–time_block_coding...

   STTD utilizes space–time block code (STBC) in order to exploit redundancy in multiple transmitted versions of a signal. STTD is one of numerous open loop transmit diversity schemes which also include Phase Switched Transmit Diversity (PSTD), Time Switched Diversity (TSTD), Orthogonal Transmit Diversity (OTD) and Space Time Spreading (STS) [1].

7. Clock recovery - Wikipedia

   en.wikipedia.org/wiki/Clock_recovery

   The term is most often used to describe digital data transmission, in which case the entire signal is suitable for clock recovery. For instance, in the case of early 300 bit/s modems , the timing of the signal was recovered from the transitions between the two frequencies used to represent binary 1 and 0.
