Mitigating the effects of interference through coding, interleaving and signal editing

Based on the fact that the performance of random error-correction decoding is insensitive to code symbols erased before its decoding process, a new approach to mitigate the effects of interference is derived. This approach consists of three basic functions: it modifies conventional interleaving, detects and deletes burst errors, and corrects random errors. Therefore this approach minimises the effects of jamming, antenna switching and nuclear deep fading. In the paper we first describe a tactic for integrating coding and interleaving. The derivation and application of a special rate-1/4 convolutional code are then illustrated, and, finally, some preliminary computer simulation results are utilised to demonstrate the effectiveness of the proposed technique.
