Implementing complex multipliers by means of polynomial products

Research output: Contribution to journalConference articlepeer-review


A new method is presented for complex multiplication. The method relies on encoding the complex numbers as seventh-order cyclic polynomials and viewing their product as an 8-point cyclic convolution. The result is that the complex multiplier is decomposed in multipliers of one fourth the wordlength of the original multiplier. These smaller multipliers are connected in a way forming a systolic array which performs the complex multiplication error free. The proposed decomposition can result in attractive VLSI implementations.
