Cambridge Consultants has developed a WiMAX simulation testbench to support the launch of Aspex Semiconductor's reference code for implementing multi-antenna basestations. The software simulates subscriber transmissions, providing an independent testing facility that can be used by developers alongside Aspex's 802.16d/e PHY baseband architecture in a familiar, PC-based software development environment. Based on the Linedancer family of processors, Aspex's WiMAX PHY reference code delivers a software-defined radio architecture and support for multi-antenna techniques such as MIMO and beam-forming. Written in MatLab, the model simulates WiMAX subscriber transmissions and channel noise, giving system developers the means to begin developing transceiver equipment and to test and verify multi-antenna 802.16 design concepts in the lab. The WiMAX subscriber model simulates an OFDM (orthogonal frequency division multiplexing) transmitter. By creating simple scripts defining standard MAC messages, developers can simulate subscriber transmissions to exercise the basestation receiver.
