چکیده

We present an open source LTE receiver framework. Using GNU Radio‘s block-based signal processing capabilities, various LTE baseband specific functionality has been implemented in dedicated easily reconfigurable blocks. These can be used to decode and analyze arbitrary channels in the LTE downlink signal. As an example we decode the Master Information Block (MIB) transmitted on the Broadcast Channel (BCH). Our work is focused on performance measurements in order to identify critical processing operations on a General Purpose Processor (GPP). By optimizing critical components, e.g. channel estimation, synchronization, we can improve the overall system performance and therefore the system‘s real-time capabilities.

Software Receiver Implementation

Preface Wireless standards are subject to rapid development and frequent changes, making old hardware obsolete at a high rate. On the other hand, the constantly increasing computational power of general purpose computers allows developers to move functionality away from hardware and specialized processors, to high-level software running on arbitrary general purpose processors. This leads to the...

Reconfigurable cognitive transceiver for opportunistic networks

In this work, we provide the implementation and analysis of a cognitive transceiver for opportunistic networks. We focus on a previously introduced dynamic spectrum access (DSA) cognitive radio (CR) solution for primary-secondary coexistence in opportunistic orthogonal frequency division multiplexing (OFDM) networks, called cognitive interference alignment (CIA). The implementation is based on ...

Low complexity MMSE interference cancellation for LTE uplink MIMO receiver

In this paper, we propose a novel low complexity minimum mean square error (MMSE) interference cancellation (IC) to minimize the residual inter-symbol and inter-antenna interference in LTE/LTE-Advanced uplink. In the LTE/LTEAdvanced base station, frequency domain equalizers (FDEs) are adopted to achieve good performance. However, in multi-tap channels, the residual interference of FDE still deg...
