REDUNDANCY CODED DATA SYSTEM |
摘要 |
A data transmission system in which data is transmitted in a form incorporating additional data providing for error correction at the receiver. The data is encoded in a transmitter using a signal mapping system which maps a number of original digits and also digits produced by a convolutional encoder. The data at the receiver is decoded using hard and soft decision decoding which can correct errors in the received data. |
