Wireless communications have been evolving in the past years in a fast way that led to the apparition of numerous standards like UMTS (3G), IEEE 802.11 (WLAN) and DVB-H. New mobile equipments should support multiple standards in order to offer the most complete set of applications to the user like telephony, mobile internet and mobile television. This paper presents a new method of implementing a high performance finite impulse response (FIR) filter in the frequency domain that is suitable for third generation communication systems. The method discussed is also an enabler for the implementation of low cost modules capable of performing filtering and fast Fourier transforms for use with the wide variety of the wireless communication standards available nowadays.
