Abstract: Massive MIMO base stations are expensive to build due to the requirement for a large number of RF transceivers and high-resolution analog-to-digital converters (ADCs). A way to reduce the implementation cost is to build the base stations with inexpensive hardware, resulting in the received signals to be coarsely quantized. To implement the data detection and decoding process in real time, fixed-point arithmetic with reduced precision is used. In this seminar, ways to reduce the cost of MMIMO base stations are investigated and the implementation techniques with reasonably sized FPGA boards are proposed. The minimum wordlength needed to maintain the Bit-Error Rate (BER) at acceptable levels, as well as the latency and hardware utilization of FPGA implementations, e.g. QR decomposition and Eigenvalue decomposition, are reported.
