<p>A multidirectional time-division multiplexing wireless data communications system can prevent erroneous data from being transmitted through a data communication line even when a bit error has occurred in transmission data. An error correcting redundant bit, obtained by performing an error correcting code operation on a low-speed continuous signal, is multiplexed to a specific vacant slot in a wireless frame. A burst signal, converted by a continuous/burst signal conversion circuit through an interleaving operation, is multiplexed to a predetermined time slot, and transmitted to a wireless area. The burst signal is received by the conversion circuit, and converted into a continuous signal through a de-interleaving operation. A division circuit divides an error correcting code to generate a syndrome. Based on the syndrome, an error position detection circuit specifies bit error position in data, and an addition circuit corrects errors.</p> |
