ACPR (adjacent channel power ratio), AltCPR (alternatechannel power ratio), and noise are important performancemetrics for digital communication systems thatuse, for example, WCDMA (wideband code division multipleaccess) modulation. ACPR and AltCPR are bothmeasures of spectral regrowth. The power in the WCDMAcarrier is measured using a 5MHz measurement bandwidth;see Figure 1. In the case of ACPR, the total powerin a 3.84MHz bandwidth centered at 5MHz (the carrierspacing) away from the center of the outermost carrier ismeasured and compared to the carrier power. The resultis expressed in dBc. For AltCPR, the procedure is thesame, except we center the measurement 10MHz awayfrom the center of the outermost carrier.

影響汽油發動機排放的最主要因素是混合氣的空燃比， 理論上一公斤燃料完全燃燒時需要14.7公斤的空氣。這種空氣和燃料的比例稱為化學當量比。空燃比小于化學當量比時供給濃混合氣，此時發動機發出的功率大，但燃燒不完全，生成的CO、HC多；當混合氣略大于化學當量比時，燃燒效率最高，燃油消耗量低，但生成的NOx也最多；供給稀混合氣時，燃燒速度變慢，燃燒不穩定，使得HC增多。在電控汽油噴射系統中采用閉環控制的方式，將空燃比控制在化學當量比附近，并在排氣系統中消聲器前安裝一個三元催化轉化器，對發動機進行后處理，是當前減少汽車排氣污染物的最有效方法。在化學當量比附近，轉化器的凈化效率最高。

This model simulates a CDMA2000 1xRTT Forward link (between Base Station and Mobile Station). In particular, it simulates the Radio Configuration 3 of a Forward Fundamental channel. The block CDMA2k: Initial settings allows you to set different parameters such as data rate, Power Control SubChannel insertion rate, spreading code index, QOSF index and the channel model.

CC386 is a general-purpose 32-bit C compiler. It is not an optimizing compiler but given that the code generation is fairly good. There are two versions one is for MSDOS/DPMI and one is for Win32. The Win32 version has a full-blown IDE capable of editing, building, and debugging windows programs included with it. However at this time debugging support for MSDOS is rudimentary at best and there is no IDE for DOS. the newest version, support windows.
