AMI编译码（归零码实验）matlab代码

以下是一个简单的AMI编码解码的Matlab代码示例：

% AMI Encoding and Decoding
% Generate a random bit sequence
bit_sequence = randi([0 1], 1, 10);
disp('Bit Sequence:');
disp(bit_sequence);

% AMI Encoding
ami_sequence = zeros(1, length(bit_sequence));
previous_voltage = 1;
for i = 1:length(bit_sequence)
    if bit_sequence(i) == 0
        ami_sequence(i) = 0;
    else
        if previous_voltage == 1
            ami_sequence(i) = 1;
            previous_voltage = -1;
        else
            ami_sequence(i) = -1;
            previous_voltage = 1;
        end
    end
end
disp('AMI Sequence:');
disp(ami_sequence);

% AMI Decoding
decoded_sequence = zeros(1, length(ami_sequence));
previous_voltage = 1;
for i = 1:length(ami_sequence)
    if ami_sequence(i) == 0
        decoded_sequence(i) = 0;
    else
        if previous_voltage == ami_sequence(i)
            decoded_sequence(i) = 0;
            previous_voltage = ami_sequence(i);
        else
            decoded_sequence(i) = 1;
            previous_voltage = ami_sequence(i);
        end
    end
end
disp('Decoded Bit Sequence:');
disp(decoded_sequence);

该代码生成一个随机的比特序列，使用AMI编码对其进行编码，然后使用AMI解码对其进行解码。输出包括原始比特序列，AMI编码后的序列以及解码后的比特序列。
