Performance Gain Evaluation from High Speed Packet Access Evolution (HSPA+)

This paper presents a study on the HSPA+ technology and the impact it have on today's mobile communication networks. To this end we study how to use features such as MIMO (Multiple Input Multiple Output) and HOM (Higher Order Modulation) and how they can increase the data rate transfer per user. The extracted results show that we can increase the data transmission rate by varying the configuration of antennas and the modulation type, obtaining the maximum theoretical order of 43.8 Mbps and 23 Mbps in Downlink (DL) and Uplink (UL), respectively using 4x4 MIMO and 64-QAM (Quadrature Amplitude Modulation) modulation. These results are obtained based on the direct application or manipulation of existing models and integrated in a simulator implemented for this purpose.
