- 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 must traverse a potentially difficult environment with scattering, reflection, refraction and so on and may then be further corrupted by thermal noise in the receiver means that some of the received copies of the data may be closer to the original signal than others. This redundancy results in a higher chance of being able to use one or more of the received copies to correctly decode the received signal. In fact, space–time coding combines all the copies of the received signal in an optimal way to extract as much information from each of them as possible. (en)
- In telecomunicazioni, la codifica di Alamouti, anche conosciuta come space-time block coding, è una forma di codifica utilizzata nella trasmissione di dati digitali, in particolare nelle tecnologie wireless. Questa codifica permette di ottenere un'alta qualità delle trasmissioni, mediante l'utilizzo di più antenne e una modalità di trasmissione che prevede la possibilità di inviare più trasmissioni delle stesse informazioni, che verranno selezionate in fase di ricezione.In pratica, con due antenne in trasmissione e una in ricezione, in presenza di fading, si riesce a realizzare un sistema di trasmissione numerica in cui la probabilità di errore tende a zero, secondo l'inverso del quadrato del rapporto segnale/rumore.
