| titleOfInvention | Self-synchronizing scrambler/descrambler without error multiplication |
| abstract | A self-synchronizing scrambler/descrambler arrangement (400) operates in two modes. In the first, or start-up mode, predetermined data is coupled to the scrambler (from 404 via 408) and transmitted (via 303) to the descrambler. This data is used to "seed", i.e., load, storage devices (407,431) in the scrambler and descrambler with the same information. After a predetermined time interval, the start-up mode is terminated, and the scrambler and descrambler each operate in a steady-state mode. In this mode, the information loaded in the scrambler and descrambler devices (407,431) are used to form (by 406,432) the scrambler and descrambler key signals. Advantageously, in the steady-state mode, the occurrence of transmission errors does not effect the contents of the storage devices in the scrambler and descrambler. Hence, the prior art problem of error multiplication is avoided. In applications where a number of coded and multiplexed data channels are communicated over the communications channel linking the scrambler and descrambler, this approach allows the use of a single scrambler/descrambler without degrading the coding benefits. |
