Abstract

In this paper a cloud version of distributed reception scenario is analyzed in automated parking system. A parking sensor has a single antenna transmitter sending data to a large number of geographically separated single antenna receive routers. This scenario is applicable in smart parking system (SPS) enabled by Internet of Things (IoT). We propose a new functional split, which enables multiple-input multiple-output (MIMO) detection in cloud server and non-binary low density parity check (LDPC) codes application in SPS. The proposed architecture is intended to increase the uplink performance significantly in shadowed scenario and in strong interference scenario, leading to significant battery power saving in IoT sensor. Among other things, such approach requires less expenses due to reduced routers complexity and fits in future 5G concepts of massive IoT.
