Robust OFDM System with ml-HIM Encoding
نویسنده
چکیده
Differential encoding is a widely used technique in the context of orthogonal frequency division multiplexing (OFDM) as an alternative to coherent channel estimation and equalization. In this paper, the performance of differential encoding using amultilag higher-order instantaneous moment (ml-HIM) in OFDM system is investigated. It is shown that by using proper order and lags, the ml-HIM decoder is capable to make a robust system against the phase distortion and the intercarrier interference (ICI) caused by phase distortion and frequency offset.

متن کاملA Complexity Reduced ML Detector on OFDM-CDM Systems in Mobile Channel
Orthogonal frequency-division multiplexing (OFDM) is one of the most promising techniques for the 4-th generation mobile system. When the OFDM system is applied to cellular environment, it is required to make the transmission scheme robust to other-cell interference (OCI). The use of code division multiplexing (CDM) has been considered to mitigate the OCI in OFDM systems. In cell boundary, it i...
متن کاملGeneralized differential encoding: a nonlinear signal processing perspective
Incoherent detection based on differential encoding has been successfully applied to phase-shift-keying (PSK) signals because it eliminates the need for carrier phase acquisition and tracking at the receiver. This paper generalizes the idea of differential encoding by using a nonlinear transformation called multilag high-order instantaneous moment (ml-HIM). The ml-HIM decoder is capable of remo...
متن کاملA Robust and Precise Solution to Permutation Indeterminacy and Complex Scaling Ambiguity in BSS-Based Blind MIMO-OFDM Receiver
The multiuser separation problem in a multi-input multioutput (MIMO) orthogonal frequency division multiplexing (OFDM) system can be represented as an instantaneous blind source separation (BSS) problem in complex domain. But reconstruction of multiuser signals suffers from permutation indeterminacy, amplitude scaling ambiguity and phase distortion which are inherent to complex BSS. This paper ...
