Improved Time Diversity for Lte over Satellite Using Split Multicode Transmission
نویسندگان
چکیده
An improved time diversity technique is proposed for deploying the 3GPP LTE airinterface over satellite mobile links. It overcomes the FEC performance loss resulting from the use of a short transmit-time-interval (TTI) in LTE. By using transport block expansion, code block segmentation, advanced rate matching and automatic retransmissions, the FEC coded block is split over as many TTIs as is necessary to break the channel correlation without any reduction in the user data rate.

Modeling and Performances Evaluation of HARQ Technique for MIMO Transmission in Downlink LTE Cellular Networks
Long Term Evolution (LTE) is designed for deployment in a variety of spectrum allocation ranging from 1.4 MHz to 20 MHz. The peak data rate envisaged for LTE is 100 Mbps in downlink and 50 Mbps in the uplink. Unfortunately, different constraints have a strong influence on system performance such as the velocity of user equipment and effect of multipath channel. To achieve data rate compliance w...

Introduction: In next generation mobile communications systems, a very high-speed data transmission under severe frequency selective fading environments is required, particularly on the down link (baseto-mobile) [1]. Recently, orthogonal frequency division multiplexing (OFDM), that transmits many narrowband data-modulated orthogonal subcarriers in parallel, has gained much attention. Meanwhile,...

متن کاملTwo Dimensional Signal Spreading in UMTS LTE: Exploiting Time-Frequency Diversity to Increase Throughput
This paper proposes a two-dimensional spreading method in UMTS Long Term Evolution (LTE). Such method brings additional time-frequency diversity which is beneficial in terms of the ability to decode transmitted dat at the receiver side under multipath fading. Additional diversity is caused by the fact that chips of transmitted signals are spread with a Walsh-Hadamard spreading sequence over sev...
