This paper addresses the problem of resource allocation in a multiservice overlapped code division multiple access (OV-CDMA) system. A joint transmission power and overlapping coefficient (transmission rate) allocation strategy is provided via the solution of a constrained convex quadratic optimization problem. The solution of this problem maximizes the aggregate throughput subject to peak transmission power constraints. The optimization problem is solved in a closed form, and the resource…

TLDR
The capacity region of code-division multiple access is shown to be convex by breaking the complicated topological structure into characteristic properties of its boundary and interior points, each of interest in itself.
Single-cell forward link power allocation using pricing in wireless networks
TLDR
This work considers forward link power allocation for voice users in a code-division multiple-access wireless network and shows how these optimal allocations can be achieved using pricing.

Distributed resource allocation for DS-CDMA-based multimedia ad hoc wireless LANs
TLDR
A distributed resource allocation protocol, known as distributed resource negotiation protocol (DRNP) that builds on the RTS/CTS bandwidth reservation mechanism provided by IEEE 802.111, and provides quality of service (QoS) guarantees through distributed control of resources in DS-CDMA based multimedia WLANs is presented.
Dynamic spreading gain control in multiservice CDMA networks
TLDR
A direct-sequence code division multiple access (DS-CDMA) network consisting of a single radio access point and a collection of wireless terminals is considered, and an explicit (closed-form) expression for the stationary distribution of the number of active class-1 and class-2 terminals is obtained, that is, the MAI level.
A scheme for throughput maximization in a dual-class CDMA system
TLDR
It is shown that the second transmission mode, which is a time-scheduled scheme for the delay-tolerant users (with hybrid CDMA/TDMA as a special case), affords a better throughput while imposing the same average power requirements as conventional transmission.

TLDR
A power control algorithm is presented which simultaneously minimizes interference and provides variable QOS contracts for different traffic types in a CDMA system and can add or drop connections dynamically while ensuring that QOS specifications are satisfied.
A new power control function for multirate DS-CDMA systems
TLDR
A closed-form open-loop power control function based on a newly defined traffic exponent and a user model that allows users to dynamically switch traffic rates for different connection applications is implemented.
