“…For instance, in speech transmission which is typically based on finite frames, the speech frames contain around 200 bits to be processed by the channel encoder [42]. In many international standards such as JD-COMA mobile systems [43], OS-COMA digital cellular systems known as Interim Standard (IS-95) [44], pan European Global System for Mobile communications (GSM) and Digital Cellular System (DCS) 1800 [45], speech frames contain 192, 192, and 189 bits respectively [42]. Hence, these results suggest that for provisioning BER requirements for short-frame applications, the quadratic interleaver is a good overall choice due to its remarkable BER in both waterfall and error floor regions compared with the performance of matrix based block interleavers.…”

Serial Concatenation of Interleaved Codes (SCICs) is emerging as a promising technology to improve the physical layer (PHY) performance of modern wireless communication systems in terms of bit-error rate (BER), mainly due to their outstanding coding gains and feasible decoding complexities. For their channel coding performance, an inter Ie aver is a critical component since the Minimum Hamming Distance (MHD) between legitimated permutations of the encoded bit sequence is directly influenced by the interleaver design. In this treatise, the construction of permutation mapping for SCICs is considered based on quadratic congruence, and the results are compared with the system using matrix-based block interleavers where the randomization is performed by storing and looking up elements in a matrix configuration. The performance evaluations are carried out in terms of BER for Single-Input Single-Output (SISO) and Multiple Input Single-Output (MISO) wireless communication systems in a femtocell propagation environment.The results reveal that employing quadratic interleavers yield lower BERs at both waterfall and error-floor regions, compared with the block interleavers.

“…In [118], which dates back to 1994, Ramsdale states that national roaming 3 is part of the specifications of the Digital Cellular System at 1800 MHz (DCS 1800), unlike the Global System for Mobile Communications at 900 MHz (GSM 900), which supported international roaming only. National roaming was introduced in the DCS 1800 to improve coverage due to smaller cell sizes at 1800 MHz (as opposed to 900 MHz).…”

Infrastructure sharing for mobile networks has been a prolific research topic for more than three decades now. The key driver for Mobile Network Operators to share their network infrastructure is cost reduction. Spectrum sharing is often studied alongside infrastructure sharing although on its own it is a vast research topic outside the scope of this survey. Instead, in this survey we aim to provide a complete picture of infrastructure sharing both over time and in terms of research branches that have stemmed from it such as performance evaluation, resource management etc. We also put an emphasis on the relation between infrastructure sharing and the decoupling of infrastructure from services, wireless network virtualization and multi-tenancy in 5G networks. Such a relation reflects the evolution of infrastructure sharing over time and how it has become a commercial reality in the context of 5G.

In this paper, we develop optimum and suboptimum receivers for jointly detecting two cochannel continuous phase modulated (CPM) signals. These receivers are b ased u p on Laurent's representation of binary CPM as the sum of a nite number of pulse amplitude modulated signals. We also provide a review of the Laurent representation and its application to the design of optimum and suboptimum single-channel receivers.
