摘要：

An efficient high-dimensional codebook design is conceived for sparse code multiple access systems. This generalized technique has the compelling benefit that its power efficiency is monotonically increased with its dimensionality. A striking further practical benefit is that this increased power efficiency is achieved without increasing the per-symbol detection complexity.
