Abstract
En krets utfører kompleks deling og dobbel kompleks multiplisering. Kretsen har et flertall av multiplikatorer. Hver i nevnte flertall av multiplikatorer anvendes i både den komplekse deling og i de doble, komplekse multipliseringer. Kretsen har også et flertall av komponenter som er i stand til å addere og subtrahere. Hver adderings- og subtraheringskomponent anvendes under den komplekse deling og den doble, komplekse multiplisering og veksler mellom operasjon som en adderer og en subtraherer mellom utførelse av den komplekse deling og den doble, komplekse multiplisering. Foretrukne, potensielle anvendelser for kretsen er i en mottaker i brukerutstyr eller en basestasjon. Kretsen anvendes i en hurtig Fourier transformasjon (FFT) basert kanal estimering eller en FFT basert data deteksjon.A circuit performs complex division and dual complex multiplication. The circuit has a plurality of multipliers. Each of said plurality of multipliers is used in both the complex division and in the double complex multiplications. The circuit also has a plurality of components capable of adding and subtracting. Each addition and subtraction component is used during the complex division and the dual complex multiplication and alternates between operation as an adder and a subtractor between execution of the complex division and the dual complex multiplication. Preferred potential applications for the circuit are in a receiver in user equipment or a base station. The circuit is used in a fast Fourier transformation (FFT) based channel estimation or an FFT based data detection.
