利用稀疏图调制和“空中”耦合实现AWGN信道容量

Achieving AWGN Channel Capacity with Sparse Graph Modulation and "In the Air" Coupling

Dmitri Truhachev

摘要:

被认为是在一个多址信道的通信。每个用户将其信号调制为冗余数据流的叠加,其中数据位的互连可以通过稀疏图来表示。接收器观察由稀疏调制图的耦合产生的信号。对迭代干扰抵消译码进行了分析。证明了空间图形耦合允许在等功率传输的情况下实现AWGN信道容量。

英文摘要:

Communication over a multiple access channel is considered. Each user modulates his signal as a superposition of redundant data streams where interconnection of data bits can be represented by means of a sparse graph. The receiver observes a signal resulting from the coupling of the sparse modulation graphs. Iterative interference cancellation decoding is analyzed. It is proved that spatial graph coupling allows to achieve the AWGN channel capacity with equal power transmissions.
