By using the Volterra kernel, the quantitative analysis of linear and nonlinear intersymbol interference at the output of the orthogonal modulators due to the nonlinear telephone channel having memory is presented when the high speed data signal is transmitted in this system.
A new constrained minimum variance distortionless response (CMVDR) receiver based on maximum likelihood (ML) estimation of multiuser for STBC MIMO CDMA system with high performance, which was used to suppress multiple access interference (MAI) and intersymbol interference (ISI) well, was proposed.
提出了 STBC MIMOCDMA 系统中一种新的基于多用户 ML 估计的带制约的最小方差无失真响应(CMVDR)接收机,能有效抑制多址干扰(MAI)和符号间干扰(ISI)。
Intersymbol Interference (ISI) always appears when the communication channel is a multi-path channel.
This paper investigates an inherent but adverse phenomenon called cyclic intersymbol interference (cyclic ISI) occurred in frequency-domain decision-feedback equalizer (FD-DFE).
Cyclic Intersymbol Interference of Frequency-Domain Decision-Feedback Equalizer: Effect and Mitigation
The shutter of the proposed system is introduced for pulse shaping to improve the intersymbol interference (ISI).
Although Constant Modulus Algorithm (CMA) is effective to equalize non-minimum phase channels blindly, it suffers from residual intersymbol interference (ISI) and large Mean Square Error (MSE) when applied to higher order constellations (QAM).
