Title:FPGAApplicationDesigninTDMASpreadSpectrumSignalTransmissionFormat
Abstract:
ThispaperpresentsadetaileddesignandimplementationofaFieldProgrammableGateArray(FPGA)-basedapplicationinTimeDivisionMultipleAccess(TDMA)spreadspectrumsignaltransmissionformat.ThemainobjectiveistoexplorethepotentialbenefitsofusingFPGAtechnologytoimprovetheperformanceandefficiencyofTDMAspreadspectrumsystems.
Introduction:
TDMAisawidelyusedcommunicationtechnologythatallowsmultipleuserstosharethesamefrequencybandbydividingthesignalintodiscretetimeslots.Spreadspectrumtechniques,ontheotherhand,involvespreadingthesignaloverawiderfrequencybandtoachievebettersignalquality,improvedresistancetointerference,andincreasedsecurity.
