In heterogeneous networks, network selection is an impor-tant task for reconfigurable mobile devices (MDs). In the reconfigurable MD architecture that has been standardized by the European Telecommu-nications Standards Institute (ETSI), the network selection functionality is handled by a software component called Mobility Policy Manager (MPM). In this paper, we present an implementation of theMPMwhereby a reconfig-urableMDconforming to the ETSI standard can select the most appropriate radio access network (RAN) to use. We implemented a reconfigurable MD test-bed compliant with the ETSI standard, and show that the network se-lection driven by the MPM enhances the throughput of the receivingMDby about 26% compared to the arbitrary network selection provided by a con-ventional reconfigurable MD without the functionality of MPM, verifying the functionality of the MPM.

In this paper, we propose a design rule of a modified quasi-cyclic structure for bit-interleaved coded modulation with iterative decoding (BICM-ID). The proposed structure is especially favorable for low-complexity hardware implementation. In addition, it will be shown that the proposed structure effectively removes low-weight codewords, which in turn greatly improves error-floor behaviors as compared to quasi-cyclic interleaver.
