Description
Summary:This paper presents a comprehensive performance analysis of a multiple layer LDM (N-LDM) system. Although previous works have proposed the use of N-LDM for delivering different services within a RΓ channel, none of them has presented results for more than three layers. What is more, a detailed analysis where the system efficiency is taken to its limit is still missing. Hence, in this work a new simulation tool has been developed, where any number of layers can be transmitted and received by using multiple layer frequency domain cancellation. On the one hand, the results address the number of services that can be simultaneously transmitted for specific user characteristics and propagation channels. On the other hand, the minimum interlayer injection level (IL) that has to be applied for correct reception has been defined and calculated for different configurations.
