From: Hadamard upper bound on optimum joint decoding capacity of Wyner Gaussian cellular MAC
Summary of optimum joint decoding capacity and the Hadamard upper bound on optimum capacity; the black solid curve illustrates the capacity using (14); the red dashed curve illustrates theoretical HUB on capacity using (20); the black dashed-dotted curve and the curve with red square marker illustrate optimum capacity and theoretical HUB, respectively, when inter-cell interference is negligible using (23); the curve with green circle marker shows capacity when inter-cell TDMA is employed using (26).
