Friends, what is Time Diversity? drolet_55 26-April-2008 11:49:25 PMComments It is used in digital communication systems. Multiple versions of the same signal are transmitted at different time instants. Posted by waqqas1 In general Time Diversity is used in digital communication systems to combat that the transmissions channel may suffer from error bursts due to time-varying channel conditions. Posted by HamidAliKhan Multiple versions of the same signal are transmitted at different time instants. Alternatively, a redundant forward error correction code is added and the message is spread in time by means of bit-interleaving before it is transmitted. Thus, error bursts are avoided, which simplifies the error correction. Posted by jzhang Time Diversity is used in digital communication systems to combat that the transmissions channel may suffer from error bursts due to time-varying channel conditions. The error bursts may be caused by fading in combination with a moving receiver, transmitter or obstacle, or by intermittent electromagnetic interference, for example from crosstalk in a cable, or co-channel interference from radio transmitters. Time diversity implies that the same data is transmitted multiple times, or a redundant error code is added. By means of bit-interleaving, the error bursts may be spread in time. Posted by sagitraz |
