摘要：Pulse Shaping Filters or Root Raised Cosine (RRC) low pass filters emerges as one of the hottest topic in field of Wireless Communication technology. Low pass filters are used for decimation and for interpolation. When decimating, low pass filters are used to reduce the bandwidth of a signal prior to reducing the sampling rate. This is done to minimize aliasing due to the reduction in the sampling rate. When interpolating, low pass filters are used to remove spectral images from the low-rate signal.In this paper, Area Efficient and Cost EffectiveTechniques for design of Pulse Shaping Filters have beenpresented to improve the computational and implementationcomplexity. Pulse Shaping Filters have been designed andimplemented by using Square Raise Cosine Filter andOptimized Multistage polyphase FIR interpolation filter, and polyphase FIR decimation filter. The results shown that the computational cost of a polyphase Decimation filter is less with comparing the computational cost of a conventional FIR filter, which can be used both at the receiver and the transmitter.
