The Broadband & Broadcast (BB) department is active in the areas of mobile communications, satellite communications, Internet-of-Things and automotive communication systems. We take new concepts and algorithms from theory, implement them and test them in simulations and in prototypes in our labs and in the field. For instance, we operate a commercial LTE-Advanced testbed network, which we use to check the interoperability of our prototypes with the LTE standard. In short, the BB department establishes a bridge between communication theory and its employment in practice.
During the past sixty years, a formidable effort has been channeled in the research of capacity-approaching error correcting codes. Initially the attention was directed to short and medium-length linear block codes, mainly for complexity reasons, while more powerful longer codes became dominant later. The interest in short and medium-block length codes (i.e., codes with information words of length 50 to 1000 bits) has been rising again recently, mainly due to emergent applications requiring the transmission of short data units like machine-type communications, smart metering networks, remote command links and messaging services. Therefore, we aim to make surveying about the possible short length block codes taking into consideration the performance and complexity. The outcome of this work should be the implementation of different short length block codes such as short binary LDPC and turbo codes, and their non-binary forms; a polar code under successive cancellation decoding; BCH codes and soft decision Reed Solomon codes.
• Learning about different types of block codes and their decoding techniques
• Design and implementation of short block length encoders and decoders in Python or Matlab.
• Making comparison between the different codes with respect to the performance and complexity
• Optional: calculating how many arithmetic operations (multiplications and additions) are needed for each code.
