A receiver (70, 80, 90) for receiving and processing digital satellite radio signals includes multiple antenna modules (12, 14, 40, 60) for receiving digital satellite radio signals, multiple processing circuits (30, 32) for converting digital satellite radio signals to low-IF or 0-IF signals, diversity circuitry (74) for selecting from among multiple low-IF or 0-IF signals, and additional processing circuitry for extracting audio and/or data from the selected signals. The system also includes automatic (94) and manual (82, 92) switches for selecting from among multiple antennas (12, 14, 40, 60), and for reducing power consumption of antenna (12, 14, 40, 60) and processing circuitry (30, 32). |
