It is shown that the cyclostationary features of a signal vary with zero padding position in the frame; thus, the cyclostationary feature differences between OFDMA signals which are received from two distinct users -even if with same CP length- can be blindly identified.
This paper analyses the outage probability for the CTI in OFDMA based HetNets.
Reference [19] presented a cross-layer design optimization for subchannel and power allocation in OFDMA system with users' queue status being considered.
Its performance compared to the OFDMA increases when the difference in channel gains is large [10].
2 shows the downlink of an OFDMA based macrocell system and the network resources in this work are partitioned based on FFR method with propose of six sectorizations where is enhancement and modification from [11].
OFDMA is the modulation used in most of the 'newest' types of wireless communication systems, including WiFi, WiMAX and LTE.
The vectors such as average interfered bitrate, average non-interfered bitrate, coupling loss percentile, interfered capacity, non-interfered capacity and signal to interference plus noise ratio (SINR) can be generated for the reference cell in particular or for the whole OFDMA system.
Several resource management schemes for OFDMA systems have been studied.
The 3GPP LTE also called release 8 specification defines the basic functionality of a new, high-performance air interface providing high user data rates in combination with low latency based on MIMO, OFDMA and an optimized system architecture evolution (SAE) as main enablers [4].
Povzetek: Opisana je metoda razporejanja za OFDMA sisteme s poudarkom na odpravljanju zamud.
Although it is necessary to control PAPR in LTE user equipment (UE), the use of SC-FDMA in the uplink rather than OFDMA means that the PAPR of the signal is no worse than that of the underlying modulation depth for QPSK or 16QAM.
