Abstract-We consider forward link power allocation for voice users in a code-division multiple-access wireless network. Admission control policies are investigated, which base a new call admission decision not only upon available capacity, but also upon the required forward link transmit power and upon the user's willingness to pay. We assume that each voice user has a utility function that describes the user's willingness to pay as a function of forward link signal-to-interference plus noise ratio. The network objective is to maximize either total utility summed over all users or total revenue generated from all users. Properties of the optimal power and code allocations are presented. Our key results show how these optimal allocations can be achieved using pricing. The analysis is complemented with a numerical study, which shows how the optimal prices and corresponding utility or revenue vary with load.

Fe/γ-Al 2 O 3 catalysts calcined at different temperatures were evaluated in the catalytic wet peroxide oxidation (CWPO) of m-cresol. BET, XRD, and 57 Fe Mossbauer spectroscopy (MS) were used to characterize the catalysts and showed that the calcination temperature changed the crystal particles of α-Fe 2 O 3 and the interactions between α-Fe 2 O 3 and the γ-Al 2 O 3 support. The reaction-condition experiments showed that changing the reaction conditions to higher reaction temperature and acidic pH promoted the degradation of m-cresol. m-Cresol was degraded completely, and TOC removal reached 51.0% after CWPO for 2 h at an initial pH of 4 and a temperature of 60°C over an Fe/γ-Al 2 O 3 catalyst calcined at 350°C (Fe/γ-Al 2 O 3 -350). Both reactions for 10 consecutive reaction cycles and for 120 continuous hours in a fixed-bed reactor showed that the Fe/γ-Al 2 O 3 -350 catalyst was stable and a promising catalyst for heterogeneous CWPO. The degradation intermediates were identified by GC-MS, and the possible degradation pathway of m-cresol was investigated.
