Microcontroller-based multiple-input multiple-output transmitter systems

Abstract

Multiple-Input Multiple_output (MIMO) Systems use multiple antennas at both the transmitter and receiver to increase data throughput and/or system reliability. An MIMO transmitter can be implemented using a variety of approaches. This work describes some of the approaches that can be used to generate the transmitted waveforms, and discuss the features and limitation of each. In particular, it shows haw a microcontroller-based system can be used for applications which require low power consumption. This thesis also describes the high-level design of a microcontroller-based MIMO transmitter. The computational speed of the microcontroller, as compared to Field-programmable Gate Array (FPGA) and Digital Signal Processors (DSP), coupled with other additional tasks which it may need to handle limit the transmitted data-rate. However, this low power and low cost design may make it attractive for some applications --Abstract, page iii
