Abstract

In wireless Multiple Input Multiple Output (MIMO) channels, the accurate detection of the transmitted information becomes complex with the order of MIMO. The complexity issues become even more pronounced with the order of modulation viz. 16-QAM, 64-QAM and 256-QAM. This paper evaluates the performance of Long Term Evolution (LTE) downlink in the extended pedestrian environment for various MIMO symbol detection techniques. Channel Detector algorithms such, Minimum Mean Square Error (MMSE), Zero Forcing (ZF) and Sphere Decoding have been evaluated for various modulation schemes. The investigation being undertaken is in terms of Physical layer BER with specific application to Spatial Multiplexing.
