—The IEEE 802.16 standard, or WiMAX, has emerged to facilitate high-bandwidth wireless access in realworld metropolitan areas, commonly referred to as 4G. In WiMAX, Hybrid Automa...
Abstract— We present the concepts and realization of a highly parallelized decoder architecture for LDPC convolutional codes and tailbiting LDPC convolutional codes. This archite...
Abstract—Under the emerging network coding paradigm, intermediate nodes in the network are allowed not only to store and forward packets but also to process and mix different dat...
The linear programming method is applied to the space Un(C) of unitary matrices in order to obtain bounds for codes relative to the diversity sum and the diversity product. Theore...
Abstract. We discuss the problem of determining the complete weight hierarchy of linear error correcting codes associated to Grassmann varieties and, more generally, to Schubert va...
