Analysis of core issues in baseband digital transmission and inter-code interference (using Matlab)
In digital communication systems, baseband digital transmission and inter-code interference are two key issues. Baseband digital transmission involves converting digital information into continuous-time signals for transmission, while inter-symbol interference refers to the mutual interference between different symbols. This article will analyze these two issues in detail and provide the corresponding source code implemented using Matlab.

Baseband digital transmission refers to the direct conversion of digital information into continuous time signals for transmission. One common method is to use pulse amplitude modulation (PAM). PAM maps each digital information to a series of pulses of varying amplitudes. The following is a simple example implemented using Matlab:
% 参数设置
T = 1; % 每个脉冲的持续时间
fs = 100; % 采样率
t = 0:1/fs:T
