In the heterogeneous wireless networks,it has been proved that the joint spectrum and power allocation can achieve network diversity gains for parallel multi-radio access in theory.This article aims to develop an effective and practical algorithm of joint subcarrier,code,and power allocation for parallel multiradio access of the downlink in heterogeneous wireless networks(e.g.,CDMA and OFDMA).Firstly,we propose a unified framework to formulate the subcarrier,code,and power allocation as an optimization problem.Secondly,we propose a resource element(subcarrier and code)scheme based on the threshold type.Simulation results show that the proposed scheme outperforms the existing algorithm for considered wireless scenarios.

This article aims to develop an effective and practical algorithm of joint subcarrier, code, and power allocation. for parallel multiradio access of the downlink in heterogeneous wireless networks (eg, CDMA and OFDMA). Firstly, we propose a unified framework to formulate the subcarrier, code, and power allocation as an optimization problem. Secondarily, we propose a resource element (subcarrier and code) scheme based on the threshold type.
