... band generation, IQ modula- tion and image rejection. Digital implementation of 90° phase shifters is in high demand as many of the digital communication s ystems use FPGAs [4-6]. The FPGAs offer ... com- putational time of a multiplier is more than that of an adder/subtractor and also occupies more hardware. In order to increase the speed and reduce the hardware cost, the coe...

... lim- itations of targeted FPGAs in term of number of dedicated multipliers, number of block RAMs (BRAMs), and memory size of each BRAM [17]. These constraints were also used in our method of re- source ... time of an adder is one clock cycle (T clk ) and that of a multiplier is 2 cycles. Regarding N complex taps filters, the throughput in terms of clock cycles of adapta...
