“…Owing to the complexity of this approach, an integrated simulation tool addressing both these aspects is expected to requires hundred of CPU time to obtain results. This suggests to separate the two aspects, and exchanging data through a suitable interface [4] - [5]. At link level, all aspects related to the transmission chain (modulation, coding, bit interleaving, etc) have to be taken into account in order to evaluate the performance metrics, typically expressed in terms of bit error rate (BER), frame error rate (FER) and block error rate (BLER) as a function of suitable definition of the carrier to interference ratio.…”

“…In such a network, the conventional approach [4] consists in considering that all the RRM procedures rely on averaged channel measurement reports provided by the mobile stations and the bases, over the fast fluctuations due to fading to provide stable information about the current electromagnetic status of the network. Assume this averaging is performed over an interval of T a seconds.…”

“…This latter aspect requires the use of performance evaluation tools characterized by the ability to follow all the rapid changes (power control, packet scheduling,..) of the network. The design of such a platform is extremely challenging as link level aspects cannot be separated by those of network level and viceversa [3][4][5]. As a matter of fact, since the Call Processing part of UMTS takes decisions every 10 ms (duration of a radio frame) or 2 ms (duration of a sub-frame when supporting HSDPA physical channels in FDD mode), and since fast power control at rate of 1500 Hz shall be implemented and bit rate shall be adapted to actual radio frequency condition, a different design of network level simulators is required.…”

The investigation of both link and network level aspects is fundamental when a thorough analysis of mobile radio systems is required. The conventional approach, based on a complete separation between the two levels, adopted in the past for the performance evaluation of second generation systems, is not enough accurate for third generation ones, characterized by the presence of both voice and data services as well as circuit and packet switched applications. Here we describe a methodology on how to interface link and network level tools and finally show an example of application.

“…The simulator uses non-averaged burst-level mapping between system and link-level simulators [5][6][7][8]. The mapping consists of two phases-first, burst-wise C/I is mapped on to raw bit error rate (in the simulated cases presented here, only two mappings are needed; one for Gaussian minimum shift keying (GMSK) and one for octagonal phase shift keying (8-PSK)).…”

This appendix describes first the fundamentals of simulation and network-level simulator (sometimes also called system simulators) functionalities. The simulators can be divided into two main categories: static simulators and dynamic simulators. The properties of these two simulation approaches are discussed and finally, the global system for mobile communications (GSM)/enhanced data rates for global evolution (EDGE) simulator used in this book are described together with the applied cellular models, algorithms and parameters. E.2 Static SimulationsStatic simulators do not model the movement of the mobiles and there is no correlation between consecutive simulation steps. Typical static simulation methodology is the following:1. Create mobiles in random places in the network. The number of mobile stations (MSs) depends on the wanted load.2. Select serving base stations (BSs) for each MS according to the received signal level.3. Adjust transmission powers of links according to, e.g. path loss criteria. After this, the interference situation in the network will be frozen.4. Execute needed radio resource management (RRM) algorithms, e.g. select coding scheme according to link quality.5. Collect statistics (carrier/interference (C/I), bit error rate (BER), block error rate (BLER), throughput, etc.).6. Repeat steps 1 to 5 (typically, a few thousand times) to get enough statistical confidence.

“…Here an exhaustive physical layer simulation for each independent link is computationally prohibitive. The link level performance abstraction is therefore used as an essential part of the system level simulation in order to predict the receiver performance under different channel conditions at a very low complexity through the use of precalculated lookup tables (LUTs) [2]. The link level performance abstraction involves both training and testing processes.…”

Abstract:In this paper a low-cost link level performance prediction technique is proposed for a single input and multiple output system. Receiver link level abstraction is used in system level simulations of large networks in order to reduce their complexity. Usually, a single lookup table is employed in link level abstraction to predict a receiver's performance under different channel conditions. In the presented work, the mean frame error rate curve of different diverse channels is proposed as the reference for performance prediction in single input multiple output systems. Its generation involves compression of the received code word into a single quality measure based on the postdetection signal to noise ratio values using nonlinear capacity, exponential, and mutual mapping functions. The overall performance difference between simulated and predicted frame error rates shows that the proposed scheme gives very good performance approximations under different modulation and coding schemes, clearly outperforming the classical line of sight channel lookup table.
