29、modulation and demodulation, the following limit shall be met for the duty cycle variation: DCSYSTEM= |DCRX DCTX| 10 % ETSI ETSI TS 125 461 V14.1.0 (2017-05)123GPP TS 25.461 version 14.1.0 Release 14Where: DCSYSTEM is the difference between the duty cycles of the transmitted and received bit streams
30、, DCTX= Duty cycle for the input bit stream, and DCRX= Duty cycle for the output bit stream. Figure 4.3.6.1: Duty cycles of the bit stream and OOK modulated subcarrier For transmission through a coaxial cable, two converters are required, one from a bit stream to OOK (modulator) and one from OOK bac
31、k to a bit stream (demodulator). Therefore half of the total duty cycle tolerance is available for each converter. For an input bit stream with a duty ratio of 50 %, the cascaded modulator and demodulator shall provide an output bit stream with a duty ratio within the limits 40 % - 60 %, measured in
