Most of advanced wireless standards, such as WiMAX and LTE, have adopted different convolutional turbo code (CTC) schemes with various block sizes and throughput rates. Thus, a reconfigurable and scalable hardware accelerator for multistandard CTC decoding is necessary. In this paper, we propose scalable maximum a posteriori algorithm (MAP) processor designs which can support both single-binary (SB)...
In this paper we present the VLSI implementation of a high-throughput enhanced Max-log-MAP processor that supports both single-binary (SB) and double-binary (DB) convolutional turbo codes. The combined hybrid-window (HW) and parallel-window (PW) MAP decoding is introduced to support arbitrary frame sizes with high throughput. A 1.28 mm2 dual-mode (SB/DB) 2PW-1HW MAP processor is also implemented in...
