Efficient implementation of the sample rate converter is extremely important to reduce the power consumption of software defined radios. This becomes even more important when sigma delta converters are used for the analog to digital conversion due to the very high oversampling rates involved. In a multistandard radio, the sample rate converter should also be capable of handling variable conversion...
This paper investigates the design of very low complexity multiplierless linear phase FIR filters for use in the channelizer of multi-standard software defined radios. A technique for reducing the hardware complexity of linear phase FIR digital filters which minimizes the adder depth and the number of adders in the multiplier block is introduced and is used to implement a multistage, multi-standard...
