Claim 7:
8. A method for downhole communication, the method comprising:
generating a first set of pressure pulses using a mud pulse generator in communication with a roll stabilized platform, the first set of pressure pulses being generated in a first pattern having a first frequency, wherein generating the first set of pressure pulses includes the roll stabilized platform actuating a pilot valve for the mud pulse generator, wherein actuating the pilot valve includes actuating a moving member connected to the pilot valve, the moving member rotating at a different rotational rate than the roll stabilized platform;
receiving the first set of pressure pulses at a first receiver;
generating a second set of pressure pulses at a downhole tool, the second set of pressure pulses being generated in a second pattern having a second frequency; and
receiving the second set of pressure pulses at a second receiver.
