Abstract: With the development of integrated circuit and computer technology, the digital communication because of its peculiar advantage has been widely used. Spectrum efficiency and bit-error-rate are two main indexes of measuring systems in the digital communication. Due to the characteristics of common transmission channels are not ideal, the digital signal produces serious intersymbol interference (ISI) after its transmission and increase the communication bit-error-rate. This is very disadvantageous for the correct decision of the receiver. So, it′s important to eliminate ISI for the improvement of transmission quality. The principle of linear equalizer based on MMSE is i
ntroduced. The simutation and design of MMSE equalizer is carried out with Matlab. Its performance is analyzed. The results show that MMSE equalizer can eliminate ISI effectively, improve the transmission characteristic of the baseband transmission system, and is an effective equilibrium receiving device.
