Simultaneous Uplink and Downlink Transmission Scheme for Flexible Duplexing
The idea of adaptive usage of uplink frequency resources for other purposes, such as downlink data transmission, has attracted researchers for many years. As an extension of the conference paper on the same subject, this article discusses the concept of applying a multichannel simultaneous uplink and downlink transmission scheme for flexible duplexing, where the middle part of the so-called upl...
متن کاملLTE Uplink Transmission
LTE and LTE-Advance communication are based on the uplink reference signals to estimate the channel characteristics. A split transmission of sounding and demodulation signaling will cause many constraints; such as layers and reference signal symbols interferences, increase in delay and reduction in the overall throughput of the LTE uplink transmission. In this paper, we propose an energy effici...
متن کاملPerformance Analysis of Downlink and Uplink Transmission Schemes in 4G LTE Using Various Modulation Techniques
In the growth of fourth-generation mobile servicing, long` c ns term evolution (LTE) is an emanate technology. In LTE the downlink model build up on orthogonal frequency division multiple access (OFDMA) and the uplink arrangement build up on single carrier frequency division multiple access (SC-FDMA).In this paper we have tendency to derive the achievement of typical elemental differences betwe...
متن کاملIterative Channel Estimation in LTE Uplink
An algorithm for iterative channel estimation using soft feedback for LTE uplink is proposed. The algorithm has low complexity compared to MMSE estimation and does not require knowledge of the channel statistics. A simple polynomial model is used for noise suppression across OFDM symbols and a DCT-based filter is used for noise suppression across subcarriers. The algorithm has been tested on se...
متن کاملUplink Power Control Schemes for LTE
In multi user environment number of users share the same radio resources. A consequence of the limited availability of radio channels in the network is that the same channel has to be assigned to many users. Thus a signal intended for a certain user will reach other users and introduce interference to their connection, and degrade the quality. Uplink power control is a key radio resource manage...
