Abstract—Selection combining cascaded with maximum-ratio combining (SC/MRC), which is particularly useful when site diversity is available, combined with low-density parity-check (LDPC) codes is able to combat the effects of fading. The biterror rate (BER) expressions of uncoded SC/MRC and SC/MRC with LDPC codes over an independent and identically distributed Rayleigh-fading channel are derived based on the Gaussian approximation approach. These expressions are also applicable to the selection combining and maximum-ratio combining as special cases. The derived expressions are in good agreement with simulation results and approach the density evolution (DE) thresholds. These expressions are able to achieve a significant reduction in computational time with a reasonable accuracy for analyzing the BER performance as compared to simulations and DE.

单片机是一种集成电路芯片，是采用超大规模集成电路技术把具有数据处理能力的中央处理器（CPU），随机存储器（ＲＡＭ），只读存储器（ＲＯＭ），多种Ｉ／Ｏ口和中断系统、定时器／计数器等功能（可能还包含显示驱动电路、脉宽调制电路、模拟多路转换器、Ａ／Ｄ转换器等）集成到一块硅片上构成的一个小而完善的微型计算机系统。(Singlechip is an integrated circuit chip. It is a central processor (CPU), random memory (RAM), read-only memory (ROM), a variety of I / O ports and interrupt systems, timer / counter and so on. The circuit, the pulse width modulation circuit, the analog multiplexer, the A / D converter, etc. are integrated into a small and perfect microcomputer system made up of a piece of silicon chip.)

汽车安全与防盗最初的电子化开始于1994年的引擎防盗(IMMO)，恩智浦半 导体(当时的飞利浦半导体)作为第一家半导体公司把RFID的电子标签技术成功 的应用于汽车电子引擎锁：通过汽车与钥匙间的125kHz的无线通讯实现电子身 份识别，来判断启动汽车引擎。这一技术极大的提高了汽车的安全性，很快就在 欧洲以及北美地区广泛应用，并在短短几年时间内使欧洲的汽车失窃率大幅降低 了90 ，因而成为整个欧洲的汽车标准配置(Automotive safety and anti-theft electronic originally began in 1994, engine anti-theft (IMMO), NXP (then Philips Semiconductors) as the first semiconductor company to RFID electronic tag technology successfully used in automotive electronic engine lock: By car keys between 125kHz and wireless communications for electronic identification, to determine start the car engine. This technology greatly improves the car' s safety, soon in Europe and North America, widely used, and in a few years time so that European auto theft rate significantly reduced by 90 , and thus the entire European automotive Standard configuration)
