Abstract :
This paper proposes a specialized convolver & correlator used for PN sequence in Chinese DTMB system [1]. It is a generic module which can achieve both convolution operation and correlation operation, so that we can reuse the module to reduce the whole area of the system. According to operational characteristics of PN sequences, we have adopted a new circuit structure so that the area of the module reduced by 83% and the power consumption reduced by about 78%.
