摘要: In a time division duplex (TDD) system, compensation measurements are made for the transmission circuitry during receive portion of TDD cycle and transmit cycle. A base station has multiple antennas spatial, as well spectral, spreading despreading discrete multitone spread spectrum (DMT-SS) communications. Each antenna its own path components components. The amplifier, example, in tend to drift their characteristics over time. invention manages sequential testing each respective antenna. measures prepares compensating weights be applied signals processed path.
