Abstract
A Multi-Input Multi-Output base station includes a plurality of transmitter blocks. Each block includes a time-domain base band signal source circuit that generates an output, a low pass filter circuit coupled to the base band source circuit that filters the output of the base band source circuit, and a signal level adjuster circuit coupled to the base band signal source circuit and the low pass filter and that adjusts the output of the base band signal source circuit based on an output of the low pass filter.
