加法器是产生数的和的装置。加数和被加数为输入,和数与进位为输出的装置为半加器。若加数、被加数与低位的进位数为输入,而和数与进位为输出则为全加器。常用作计算机算术逻辑部件,执行逻辑操作、移位与指令调用。在电子学中,加法器是一种数位电路,其可进行数字的加法计算。在现代的电脑中,加法器存在于算术逻辑单元(ALU)之中。 加法器可以用来表示各种数值,如:BCD、加三码,主要的加法器是以二进制作运算。由于负数可用二的补数来表示,所以加减器也就不那么必要。-The adder is generated the number of and apparatus. Addend and augend input sum and carry bits of the output means is a half adder. If the addend, augend and the low decimal input, and the sum and carry output is a full adder. Commonly used for computer arithmetic logic unit, perform logical operations, shift instruction calls. In electronics, the adder is a digital circuit, which may be a digital sum. In modern computers, the adder is present being in the arithmetic logic unit (ALU). Adder can be used to represent various values​ ​ , such as: BCD, plus three yards main adder based on binary for computing. Negative two s complement available to represent the addition and subtraction is not so necessary

You can learn BPSK modulation in OFDM Systems BPSK means binary phase shift keying modulation. Basically OFDM uses fft/ifft modulation. and add cyclic shift and remove to cancel inter-symbol-interference.

循环码最大的特点就是码字的循环特性,所谓循环特性是指:循环码中任一许用码组经过循环移位后,所得到的码组仍然是许用码组,也就是说,不论是左移还是右移,也不论移多少位,仍然是许用的循环码组. 译码过程 第一步:由接收码字  Rx与监督矩阵相乘得出错误图样S; 第二步:判断S是否为零。若不为零,则出错。在假定至多只有一位错的情况下,可以有效地译出相应的信息码字。 第三步:在出错的情况下,将S与标准监督矩阵对比,得出错误的比特位并进行更正得出前四位为信息码字。-Ring Code biggest feature is the cycle characteristics of code words, the so-called cycle characteristics means: a cyclic code in any code group after the allowable cyclic shift, the resulting code group is still permissible code group, that is, whether It is left or right, regardless of the number of shift bits still set cyclic code with Xu. The first step in the decoding process: the received codeword   Rx and monitoring matrix obtained by multiplying the error pattern S Step two: Analyzing S is zero. If zero, the error. Under the assumption that at most only one wrong circumstances, can be effectively translated to the corresponding information code word. The third step: in case of an error, the S criteria for comparing and monitoring matrix draw the wrong bit and make corrections to information obtained first four codewords.
