“…The SNR requirements are based on the model [6] and are modulation specific. When considering the EVM requirements, we adopted the following figures: QPSK = −20dB, 16 QAM= −20dB, 64QAM=-26dB and 256 QAM= −34dB.…”

“…If the range is shorter than the link margin for the maximum rate, the PA power control can be used to reduce output power, and thus both lower power consumption and limit co-channel interference. The RF modelling approaches are illustrated in [16] to highlight the impacts of neglecting RF modelling when estimating range vs. data rate. …”

“…System level parameters and assumptions are collected in Table I. The achievable data rate, RMax, which can be scaled to system bandwidth and modulation scheme as [16] Max = ( FFT − ACI ) log 2 ( Mod ) OFDM (2) where denotes coding rate, NFFT is the size of Fast Fourier Transform (FFT), NACI is the number of guard band subcarriers for mitigating the adjacent channel interference (ACI), MMod is the modulation order and tOFDM is the symbol duration including Table II. The maximum rate for single stream requires 256QAM which is extremely challenging to achieve with realistic receiver RX and TX nonidealities in practice.…”

Abstract-Wideband fifth generation (5G) systems utilizing high carrier frequency and multiple-input multiple-output (MIMO) raise major challenges for the system design. Wave propagation and practical hardware tradeoffs at higher frequency ranges provide new boundary conditions for the implementation. This paper addresses system performance boundaries and the analysis method towards multibeam communications at mmW. We combine analysis from antennas and propagation to the RF transceiver specifications and beamforming requirements. Realistic propagation model and antenna implementation is used to generate beam-specific path gains and provide a wide variety of user scenarios. Using this approach, system level interdependencies and RF performance boundaries can be verified with different antenna configurations in various propagation environments. As an example, we present MIMO link budget analysis targeting 10 Gbits/s for multiple devices in the office scenario at 27 GHz.

“…To cope with higher data rates demand for future wireless devices and services, requirements of broader bandwidth and signal to noise ratio (SNR) of radio links have increased [1]. Bandwidth of a few hundred MHz is not available in currently used frequency bands, which leads us to unused bands available in millimeter wave or centimeter wave frequencies.…”

“…A communication model and link budget analysis for a future wireless system is proposed in [1]. It has been shown that a minimum SNR of 33 dB is required for implementing higher order modulation schemes such as 256 QAM to achieve maximum non-coded data rate of more than 3 Gbits/s at 500 MHz bandwidth in a communication link.…”
