Consider the jointly optimum detector defined in Problem 16.8 for the two-user, synchronous CDMA system.

a. Show that the asymptotic efficiency for this detector for user 1

b. Plot and compare the asymptotic efficiencies of the jointly optimum detector and the conventional single-user detector for ρ = 0.1 and ρ = 0.2.
