Constellation-constrained capacity for trellis code multiple access systems
Trellis code multiple access (TCMA) is a narrow-band multiple access scheme. There is no bandwidth expansion, so users are using the same bandwidth as one single user. The load (the number of bits per channel use) of the system is therefore much higher than the load in, for example, conventional CDMA systems. It is shown here that the maximum number of users in a TCMA system is usually modest. ...
متن کاملNon-Orthogonal Multiple Access (NOMA) for Future Radio Access
This paper presents a non-orthogonal multiple access (NOMA) concept for future radio access (FRA) towards the 2020s information society. Different from the current LTE radio access scheme (until Release 11), NOMA superposes multiple users in the power domain although its basic signal waveform could be based on the orthogonal frequency division multiple access (OFDMA) or the discrete Fourier tra...
متن کاملDownlink Non-Orthogonal Multiple Access (NOMA) in Poisson Networks
A network model is considered where Poisson distributed base stations transmit to N power-domain non-orthogonal multiple access (NOMA) users (UEs) each that employ successive interference cancellation (SIC) for decoding. We propose three models for the clustering of NOMA UEs and consider two different ordering techniques for the NOMA UEs: mean signal power-based and instantaneous signalto-inter...
متن کاملAspects of Control Signaling in Wireless Multiple Access Systems
From its first appearance, wireless communications has changed the life for many people worldwide. Currently, more than half of the world’s population are using wireless devices for various purposes on a daily basis. While the early wireless systems could provide simple and specific low-rate services, today’s systems can support a variety of more advanced services some of which require high dat...
متن کاملAllocation of multiple services in multi-access wireless systems
This paper discusses principles for allocating multiple services onto different sub-systems in multi-access wireless systems. Favorable near-optimum sub-system service allocations that maximize combined multi-service capacity are derived through simple optimization procedures. These favorable service allocations are either characterized by that the relative resource cost for supporting services...
