CHALLENGES IN MIMO DESIGN

MIMO systems deliver greater performance, but with additional cost and power consumption. Competitive pressures of consumer markets impact tolerable cost (area), while thermal and battery life constraints limit tolerable power consumption in wireless portable devices. Additionally, mixed signal issues including coupling and cross-talk become critical in integrated high performance wireless systems which co-locate the digital circuitry with the analog RF electronics. Lastly, the quest for ultra-low cost solutions leads to additional systems-level integration of CPUs and other peripherals.
