循环编码整数强迫均衡

Cyclic-Coded Integer-Forcing Equalization

Or Ordentlich, Uri Erez

摘要:

考虑了一个具有加性高斯噪声的离散时间码间干扰信道,其中只有接收机知道信道的冲激响应。提出了一种将判决反馈均衡与信道编码相结合的方法,其中解码先于符号间干扰的去除。这是通过结合最近提出的整数强制均衡方法与循环分组码。信道冲激响应被线性均衡为整数值响应。然后,通过利用循环码在(循环)整数值卷积下闭合的属性来利用这一点。该方案的性能上的显式界限也来自。

英文摘要:

A discrete-time intersymbol interference channel with additive Gaussian noise is considered, where only the receiver has knowledge of the channel impulse response. An approach for combining decision-feedback equalization with channel coding is proposed, where decoding precedes the removal of intersymbol interference. This is accomplished by combining the recently proposed integer-forcing equalization approach with cyclic block codes. The channel impulse response is linearly equalized to an integer-valued response. This is then utilized by leveraging the property that a cyclic code is closed under (cyclic) integer-valued convolution. Explicit bounds on the performance of the proposed scheme are also derived.
