WebbPulse-shaping filters, however, like the root raised cosine filters used in WCDMA and TD-SCDMA, are usually not considered in estimating the EVM. The reason is that a transmit pulse-shaping filter is matched at the receiver with an identical receive pulse-shaping filter to form, as in the case of WCDMA and TD-SCDMA, for example, a raised cosine filter. WebbThis component generates a message using ASCII characters, converts the characters to bits, and prepends a Barker code for receiver frame synchronization. This data is then modulated using QPSK and filtered with a square root raised cosine filter. Channel. This component simulates the effects of over-the-air transmission.

In signal processing, a root-raised-cosine filter ( RRC ), sometimes known as square-root-raised-cosine filter ( SRRC ), is frequently used as the transmit and receive filter in a digital communication system to perform matched filtering. This helps in minimizing intersymbol interference (ISI).
