1 MIMO Development Efforts at Virginia Tech S. Ellingson 1, R. Mostafa 2 & J. Reed 2 {ellingson,ramostaf,jhreed}@vt.edu 1 Virginia Tech Antenna Group (VTAG) 2 Mobile & Portable Radio Research Group (MPRG) Bradley Dept. of Electrical & Computer Engineering Virginia Polytechnic Institute & State University 340 Whittemore Hall, Blacksburg VA September 19, 2004 Slide 1
2 MIMO at Virginia Tech Virginia Tech is interested in all aspects of MIMO: MIMO channel physics MIMO communication theory Practical implementation (HW, SW, Systems, & Networks) This talk: Evolution of a serial-bus based data aggregation scheme for array receivers Full presentation (including more details on other efforts) available: Slide 2
3 Array Receiver Architectures A MIMO communications link or channel measurement system consists of An array transmitter An array receiver Array transmitters are easy Array receivers are hard Data Aggregation (interconnects) Processing Throughput (logic density) Slide 3
4 SHF Array Experimental (SAX) 16-Channel Digital Receiver (PC with A/D cards) Classical Polled Bus Data Aggregation MIMO Channel Measurement Project ( ) SHF Rack (24xx 435 MHz) UHF Rack ( MHz) A/D Conditioning, Power, and Cal Rear View of Rack Slide 4
5 SAX: On-the the-fly Data Display Slide 5
6 SAX: Field Eval of MIMO Capacity Ideal N T =2 Ideal N T =8 Measured N T =8 Measured N T =2 Measured N T =1 (LOS) (Behind Building) Slide 6
7 SAX: Lessons Learned Limitations of Polled Bus Architecture Data Aggregation Processing Throughput MIMO Field Studies Easy to be overrun by complexity, yet: Traditional architectures are too slow -> > Time IS money Near real time monitoring is GOOD (less wasted effort when things s go wrong!)
