Polar codes are a new type of codes for forward error correction that can achieve the capacity of many practically relevant channels. Polar codes differentiate themselves from other, well established capacity achieving codes by the fact that they follow a systematic construction that yields well understood performance guarantees. Furthermore, the encoding and a capacity achieving decoding procedure of polar codes can be realized with an, at first sight, favorable complexity. Hence, these codes have received significant attention in the information-theory community. With this project, we are proposing a 2 year research effort that focuses on the practically relevant implementation aspects of polar codes with the objective to realize corresponding decoders that are competitive to decoders for established codes, both in terms of performance and complexity. To this end, we consider jointly both the algorithm and the VLSI architecture side. We believe that besides the actual decoder implementations itself these investigations will be instrumental in answering the question if and how polar codes can play a major role in future wireless and wireline communication standards. Our results will be particularly important when considering this new type of codes as competitors for established, already very well performing codes such as LDPC and Turbo codes in applications for which either low power or very high throughput are key requirements.
