The RRC filter is characterised by two values; β, the roll-off factor, and Ts the reciprocal of the symbol-rate. The impulse response of such a filter can be given as : , though there are other forms as well.

WebThe upsampled signal is passed through a squared root-raised cosine (SRRC) filter. In this way, each symbol of the message initiates an SRRC pulse that is scaled by the value of the symbol (either 1 or -1). The peaks of adjacent pulses are sps samples apart. The baud rate (which refers to the number of symbol changes that occur each second) is ... WebHierarchical block for RRC-filtered differential BPSK modulation. The input is a byte stream (unsigned char) and the. output is the complex modulated signal at baseband. @param samples_per_symbol: samples per baud >= 2. @type samples_per_symbol: integer. @param excess_bw: Root-raised cosine filter excess bandwidth.
