A multicarrier QAM modulator has been developed and implemented with programmable logic devices (PLDs). The multicarrier QAM modulator contains four CORDIC based QAM modulators. A conventional QAM modulator needs two multipliers, one adder and sine/cosine ROMs. The designed CORDIC based QAM modulator has about the same logic complexity as the two multipliers and the adder with the same word sizes. The multicarrier QAM modulator was designed to fulfil the spectrum and the error vector magnitude (EVM) specification of the wideband code division multiple access (WCDMA) system
