Measurement-based Performance Evaluation of WiMAX and HSDPA (2009)
Abstract / truncated to 115 words
In this work, a realistic physical layer performance evaluation of High Speed Downlink Packet Access (HSDPA) as well as IEEE 802.16-2004, commonly referred to as Worldwide Inter-operability for Microwave Access (WiMAX), is provided. The performance evaluation is carried out in two measurement campaigns that took place in an alpine and an urban environment. Both, WiMAX and HSDPA use adaptive modulation and coding to adapt the channel coding rate and the size of the symbol alphabet to the current channel conditions. Additionally, both systems allow for multiple transmit and multiple receive antennas to increase the spectral efficiency and the reliability of the transmission. While WiMAX utilizes multiple transmit antennas by simple Alamouti space-time coding, HSDPA implements ... toggle 11 keywordsMIMO – wimax – HSDPA – testbed – vienna mimo testbed – measurement – physical layer – throughput – achievable throughput – mutual information – channel capacity
