A novel channel based rescheduling scheme for modern turbo convolution code is proposed by the inclusion of suboptimal and low-complex max-log-MAP algorithm. Demands for dedicated custom solutions in mobile communications and its related applications leads to a reconfigurable architecture for Turbo convolution code. This study comprises the design and performance evolution of the proposed reconfigurable architecture for channel coding scheme in MIMO-High Speed Downlink Packet Access (MIMO-HSDPA). To attain effective performance close to shannon limit in a multi channel system, flexible reconfigurable architecture is realized with 28 nm cyclone V GX 5CGXFC5C6 FPGA. We achieved throughput of 13.5 Mbps compared with the conventional HSDPA standards while consuming 53 mW.
