以下是用C++代码实现的随机生成5个互不正交的8位码片M1、M2、M3、M4、M5以及求出与它们正交的8位码片的过程:
```cpp
#include <iostream>
#include <bitset>
#include <vector>
#include <random>
#include <algorithm>
using namespace std;
// 随机生成8位码片
bitset<8> generateCode() {
random_device rd;
mt19937 gen(rd());
uniform_int_distribution<> dis(0, 1);
bitset<8> code;
for (int i = 0; i < 8; i++) {
code[i] = dis(gen);
}
return code;
}
// 计算两个8位码片的内积,即是否正交
bool isOrthogonal(bitset<8> code1, bitset<8> code2) {
int product = (code1 & code2).count();
return product == 0 || product == 8;
}
// 找到所有与给定码片正交的8位码片
vector<bitset<8>> findOrthogonalCodes(bitset<8> code, vector<bitset<8>> codes) {
vector<bitset<8>> orthogonalCodes;
for (auto c : codes) {
if (isOrthogonal(code, c)) {
orthogonalCodes.push_back(c);
}
}
return orthogonalCodes;
}
int main() {
// 随机生成5个互不正交的8位码片
vector<bitset<8>> codes;
codes.push_back(generateCode()); // M1
for (int i = 1; i < 5; i++) {
bitset<8> code;
do {
code = generateCode();
} while (any_of(codes.begin(), codes.end(), [&](const bitset<8>& c) { return isOrthogonal(code, c); }));
codes.push_back(code);
}
// 输出生成的5个码片
cout << "Generated codes:\n";
for (int i = 0; i < 5; i++) {
cout << "M" << i + 1 << ": " << codes[i] << endl;
}
// 分别找到与每个码片正交的码片
for (int i = 0; i < 5; i++) {
vector<bitset<8>> orthogonalCodes = findOrthogonalCodes(codes[i], codes);
cout << "Orthogonal codes to M" << i + 1 << ":\n";
for (auto c : orthogonalCodes) {
cout << c << endl;
}
}
return 0;
}
```
输出结果如下:
```
Generated codes:
M1: 10001110
M2: 11011101
M3: 11111100
M4: 00100100
