| () |
| Abstract: |
| Aiming at odd bit error in TDMA broad band wirless access systems,this paper designs a high-efficient 7/8 self-orthogonal convolutional encoder and a decoder with feedback structure.Application of 7/8 self-orthogonal convolutional coding leads to greatly improved bit error performance of broad band wirless access systems. For phase illegibility and synchronization loss of decoder,this paper gives a universal solution that can obtain 3dB power gain and acquire synchronization between encoder and decoder quickly. |
| Key words: Microwave digital transmission,TDMA broad band wirless access system,7/8 self-orthogonal convolutional coding, |
