Abstract

PURPOSE:To increase the degree of freedom for setting the distribution rate of a mis-reception rate and a critical rate by deciding the acceptance/rejection of a decoded word output corresponding to the combination between an erroneous pattern and quality information. CONSTITUTION:An error pattern E consists of sets of error component ei of each component ri of a received word R and a quality information register 3 receives the quality information qi corresponding to each component ri of the received word, stores it and outputs the quality information Q. Then a critical region circuit 5 outputs A=1 (rejection) when the logical state of ei=0 (no error) and qi=1 (quality deterioration) takes place at least one symbol position (i) so as to detect the rejection condition due to the production of the quality deterioration information not included in the symbol location representing an error. Thus, either the rejection rate of the code or the mis- acceptance rate is set continuously in a prescribed range, and the degree of the freedom of the distribution rate setting of the both is improved.
