.A Linear- Programmiiig Design Language and its Plpplication to Data-Transmission Filters
Dean W. Lytle · 1991
This paper introduces FF, a new linear-programming tlesigii language, and uses a detailed design example in FF to preseiit IICW techniques for the design of transmit and rculive FIR. filters for digital communication. In tlie example transmit filter, after the usual analog reconstruction filtkr is modified to place its steep rolloff where it will ea5e tlie requirements on the FIR filter, the latter c;iti tlicir IIC designed so that the combined spectral rehpoiiw or tlic analog aiitl FIR filters will be root Nyquist, iiicset a regiilatory mask, and minimize interference with ;itl,jaceiit. chi~iinels. The choice of a transmit-filter phase response is Iiased 011 the resulting peak transmit-power rccliiii.(:tiiciit. An analog/l~lll coin1)in;ltion receive filter is hiiiiilarlp tlcsignetl to sat,isfy requirenients on ISI, degree til tnatcli to the transnlittkr, and adjacent-channel iiiterfcrciicc. The flexibility of FF permits this scheme to be c:isily adapted to particular system requirements.
