Abstract :
This paper is concerned with the performance and cost analysis of different pulse shaping filters such as raised cosine, finite impulse response (FIR) Nyquist, FIR half-band and infinite impulse response (IIR) linear phase half-band for wireless applications. Note that the pulse shaping is the process of changing the waveform of transmitting pulses to reduce the interferences keeping a signal in an allotted bandwidth. This paper proposes an optimal design for the pulse shaping filters to reduce their effective costs in the area of wireless communication applications. Here, we analyze the performance of pulse shaping filters based on the minimum stop band attenuation required to suppress the inter-symbol interference (ISI) and inter-channel interference (ICI). Finally, we compare the performance of raised cosine, FIR Nyquist, FIR half-band and IIR linear phase half-band filters in terms of bit-error rate (BER) and hardware requirements. Our results demonstrate that the hardware implementation costs for the FIR Nyquist, FIR half-band and IIR half-band filters are about 60% to 90% less than the raised cosine filter.
