Flexible Spectrum Control and Receiver Performance Improvement Technologies for B3G Wireless Systems

This paper will discuss trend and our views on the flexible spectrum control and receiver performance improvement technologies as a part of capacity maximization technologies for beyond third generation (B3G) systems. First of all, we will discuss dynamic spectrum control techniques that can minimize intra- and inter-system interference for both multi-carrier (MC) and single-carrier (SC) systems, thereby maximizing upper-limit of channel capacity. We will also discuss receiver performance improvement strategies as a part of capacity maximization technologies for MC and SC systems, especially joint operation of the adaptive equalizer and decoder using EXIT chart analysis for MC and SC systems
