Title
POPS-OFDM with different Tx/Rx pulse shape durations for 5G systems
Abstract
An increased user demand for high data rate wireless networks and a growing number of connected devices with high mobility of terminals lead research activities to investigate how to go beyond the Fourth Generation (4G) wireless systems capabilities [1-2]. This results in the Fifth Generation (5G) which is expected to meet a manifoldness of wireless communication services [1-2]. However, this mobility can dramatically damage the waveforms orthogonality that is induced in transmission schemes like the Orthogonal Frequency Division Multiplexing (OFDM) systems, which is the main transmission scheme that 4G systems are built on. The deterioration of the waveforms orthogonality in OFDM signals will result in oppressive Inter-Carrier Interference (ICI) and Inter-Symbol Interference (ISI), which leads to significant performance degradation in OFDM systems. In this context, a dynamic waveform construction referred as Ping-pong Optimized Pulse Shaping-OFDM (POPS-OFDM) [3-5] presents an attractive candidate for the physical layer of 5G systems. This innovative approach banks on a non-orthogonal future wireless multi-carrier scheme with a malleable waveform, which would represent an interesting solution that potentially reduces the ISI and ICI and also minimizes the energy spreading. In this paper, we go further by analyzing POPS-OFDM performance when the Tx/Rx waveform support durations are different. This aspect is motivated by the sense to reduce the user equipment's complexity (Tx side) since the mobile phone is limited in terms of power and computation. Simulation results are provided to show that the POPS-OFDM characteristics make this waveform a powerful candidate for 5G systems.
