AREA EFFICIENT & COST EFFECTIVE PULSE SHAPING FILTER FOR SOFTWARE RADIOS

In this paper area efficient and cost effective techniques for design of pulse shaping filter have been presented to improve the computational and implementation complexity. Pulse shaping filters have been designed and implemented by using Raised cosine filter, Nyquist filter and optimized half band filters for software defined radio (SDR) based wireless applications. The performance of different filters is compared in terms of BER and hardware requirements. The results show that the BER performance of the optimized designs is almost identical to the Raised cosine filter with significant reduction in hardware requirements. The hardware saving of 60% to 90% can be achieved by replacing the Raised cosine filter with proposed filters to provide cost effective solution for wireless communication applications.
