Additional Parameter --- Total OOBE Suppression is the sum of all these factors: Available suprression [*totalsuppression*] = *${totalsuppression} dB* > a. Usually Transmitters and Receiver Stations employ **additional filters** to suppress adjacant band leakage. Adjust *${filtersuppression}dB* to adjust. Transmiter filter suppression can be accounted to true implemented "ACLR", for e.g. though the 3GPP specifications has *~-45dBc*, the actual products will have values even below *60~70dBc*, > b. When IMT Stations are **transmitting** towards mobile terminals, the gain towards FSS stations or non-intended stations is the off-axis gain= *${txoffaxisfactor} dB*, this could be a from statistical term, based on IMT downtilt and beamforming etc. > c. When the Fixed **receivers** (FSS/FS) are usually not looking towards the IMT, especially when their antennas are directional, the receive antenna gain *${rxoffaxisfactor} dB* towards the IMT Transmitter is lower (based on HPBW) and is called the \`off-axis gain\`. > d. Additional Margin can be provided through ensuring addtional \`coupling Loss\` *${couplingMargin}dB* to meet the necessary ${totalsuppression} to meet interference requirement. }`33:Taff,function plotMask(fc = 0, bw = 1, psd = 0, suppress = 0) { fc = fc || 0; bw = bw || 1; psd = psd || 0; // suppress = suppress || 0; psd = psd - suppress; var caption = [txoffaxisfactor, rxoffaxisfactor, filtersuppression, couplingMargin].join( "+" ) + " = " + totalsuppression + " dB"; var mask = [ { f: fc + -2.5 * bw, p: -48 + psd - filtersuppression }, { f: fc + -2 * bw, p: -48 + psd - filtersuppression }, { f: fc + -bw, p: -44.2 + psd - filtersuppression }, { f: fc + 0, p: 0 + psd }, { f: fc + bw, p: -44.2 + psd - filtersuppression }, { f: fc + 2 * bw, p: -48 + psd - filtersuppression }, { f: fc + 2.5 * bw, p: -48 + psd - filtersuppression } ]; // var psd = txpowerpsd.dBmMHz(); var xtra = [ psd + -44.2 - filtersuppression, -13, psd + -48.2 - filtersuppression, units.N0.dBmMHz() ]; if (!showNoise) { xtra = xtra.slice(0, 3); } var adjbw = 36; var IbyN = -12; // density dBm/MHz var adjchannel = [ { f1: fc + bw / 2, f2: fc + bw + adjbw, p: IbyN + N0.dBmMHz() } ]; var frange = []; return Plot.plot({ caption: "Fig: IMT Base-station emission masks (tx,rx,filter,coupling) dB =" + caption, grid: true, y: { grid: true, label: "dBm/MHz", domain: [ymin, ymax] }, x: { grid: true, label: "f (MHz)" }, marks: [ Plot.line(mask, { x: "f", y: "p", curve: "step", strokeDasharray: [5, 0] }), Plot.ruleY([IbyN + N0.dBmMHz()], { stroke: ["orange"], strokeDasharray: [5, 1] }), Plot.rectY(adjchannel, { x1: "f1", x2: "f2", y2: "p", y1: N0.dBmMHz(), fill: "green", fillOpacity: 0.25, strokeDasharray: [5, 0] }), Plot.rectY([psd], { x1: fc + adjbw, x2: fc + 2 * adjbw, y1: "p", fill: "lightgreen", fillOpacity: 0.1, strokeDasharray: [5, 0] }), Plot.ruleX([fc], { stroke: ["red", "green", "red"], strokeDasharray: [5, 1] }), Plot.ruleY(xtra, { stroke: ["red", "green", "red", "orange"], strokeDasharray: [5, 1] }), Plot.textY(xtra, { fill: "blue", x: fc + bw * 4.5, text: [ (psd + -44.2).toFixed(2) + " dBm/MHz", -13 + " dBm/MHz", (psd + -48.2).toFixed(2) + " dBm/MHz", units.N0.dBmMHz() + " dBm/MHz" ], textAnchor: "end", dy: -5 }), Plot.textY([IbyN + N0.dBmMHz()], { fill: "blue", x: fc, text: [ "Allowed Interference : " + (IbyN + N0.dBmMHz()).toFixed(2) + " dBm/MHz" ], textAnchor: "start", dy: -5 }) ] }); }34:T476,
