In cellular communication systems, the same carrierfrequency is re-used at spatially separated base stations (BSs) to efficiently utilize the limited bandwidth. Therefore, the channel capacity is limited by the co-channel interference (CCI) from the neighboring co-channel BSs. To reduce the CCI, it is necessary to increase the frequency-reuse factor (the number of different channel groups). How...

after central nervous system (cns) injuries, the regeneration process does not work out well except for remyelination process. this remyelination capacity in cns can be mentioned as a worthy example of stem/precursor cell-mediated renewal process. remyelination in cns is mediated by schwann cells which act mainly as remyelinating agents in peripheral nervous system (pns) but several studies hav...

Arıkan’s polar coding, is by now a well studied technique that allows achieving the symmetric capacity of binary input memoryless channels with low complexity encoding and decoding, provided that the polar decoding architecture is used and the decoding metric is matched to the true channel. In this paper, we analyze communication rates that are achievable when the polar coding/decoding architec...

In this chapter we provide a brief introduction to multidimensional codes. In particular, we focus on product codes and other similar codes that use parity checks over multidimensional arrays. We present a brief introduction to product codes and their properties. We then focus on multidimensional codes based on single parity-check constituent codes. We provide two applications that illustrate t...

Abstract—In this paper, the concept of composibility of the total channel capacity of the system of channels composed of two independent subsystems of channel is discussed. This system of channels is a function of entropies of the subsystems. Here, we show that the generalized entropies, the Tsalli’s entropy, the normalized Tsalli’s entropy and the Kapur’s entropy are compatible with the compos...
