Abstract :
The upcoming IEEE WiMax 802.16e standard, also referred to as WirelessMAN (2005), is the next step toward very high throughput wireless backbone architectures, supporting up to 500 Mbps. It features as an advanced channel coding scheme low-density parity-check codes. The decoding of LDPC codes is an iterative process, hence many data have to be exchanged between processing units within each iteration. The variety of the specified codes and the envision of different decoding schedules for different codes pose significant challenges to an LDPC decoder hardware realization. In this paper, we present to the best of our knowledge the first published LDPC decoder architecture capable to process all specified WiMax LDPC codes. Detailed synthesis and communications performance results are shown in addition
