专利汇可以提供Space diversity system专利检索,专利查询,专利分析的服务。并且PURPOSE: To improve the characteristic of an error rate by providing an error rate supervisory section generating a signal relating to the error rate by a data being the result of demodulation and identification of a reception signal synthesized by a synthesizer, and using a pseudo error signal obtained through the digital conversion of the reception signal so as to control a phase shifter.
CONSTITUTION: A base band signal is identified by an A/D converter 91 being an identification section 9 and the number of prescribed bits of identification data is outputted. An error rate supervisory section 7 ORs exclusively low-order 2-bit by exclusive OR circuits 7a, 72 at each channel, each exclusive OR output is inverted by inverters 73, 74 respectively and integrated by integration devices 75, 76 to form a pseudo error rate corresponding to the error rate. A signal representing the pseudo error rate from the error rate supervisory section 7 is inputted to a controller 5 to control a phase shifter 6 to be supervised thereby decreasing the pseudo error rate. Thus, since the phase shifter is controlled by a control signal relating directly to the error rate, the error rate is improved.
