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.

说明：  该源代码为基于AVR单片机的温度加热控制系统的源程序。测温采用的的是热敏电阻，加热控制采用的是PID算法。另：编译器我用的是CVAVR 版本号是1.25.7a(The source code for AVR-based single-chip temperature heating control system of the source. Temperature measurement is used in thermistor, heating control PID algorithm is used. The other: the compiler I use is CVAVR version 1.25.7a)
