Among its specialized equipment is a laboratory-built mobile robot that enables automated propagation measurements in and around buildings. A 500 MHz spread-spectrum channel sounder provides measurements and modem testing up to 30 GHz. An adaptive antenna testbased based on quad 96000 processors has been developed to study capacity improvements in CDMA systems. MPRG has developed software tools that are in use by hundreds of companies and universities. The Radio Frequency lab has a wideband spread spectrum measurement system developed inhouse.
Students use the system for conducting indoor and outdoor RF measurements.
There are also ongoing projects for developing narrowband transmitters for the cellular band, hardware for real-time bit error rate simulation, and a mobile robot for automated measurements. The Communications and DSP lab focuses on implementing novel communication system architectures and signal processing algorithms in the fields of spread-spectrum transceiver design, adaptive filtering, adaptive antenna arrays, and speech coding. Some of the projects that have been developed are a Frequency Hopping pocket radio and an adaptive CDMA receiver. Work is currently focused on building the world's first multiuser CDMA base-station and a CDMA adaptive antenna array.
