Fig. 2From: Near-channel classifier: symbiotic communication and classification in high-dimensional spaceInteger-HDM encoder and decoder: binary string \({\mathbf {u}}\in \lbrace 0,1\rbrace ^k\) is encoded to HD superposition \({\mathbf {x}}\in {\mathbb {Z}}^D\) which is transmitted over an AWGN channel. The received vector \({\mathbf {y}}\) is finally decoded using an iterative unit-feedback decoder with unit feedback yielding the estimation \({\hat{\mathbf {u}}}\)Back to article page
