1. A downhole communication system, comprising:
a downhole tool of a bottom hole assembly, the downhole tool configured to control a first mud pulse generator to generate a first set of pressure pulses in a drilling fluid in a first pattern, the first pattern including first encoded data; and
a roll stabilized platform downhole from the downhole tool, the roll stabilized platform including:
a turbine rotatable in response to the set of pressure pulses in the drilling fluid;
a processor; and
memory, the memory including programmed instructions which, when accessed by the processor, cause the processor to:
decode the first encoded data based on rotation of the turbine; and
control the first mud pulse generator or a second mud pulse generator to generate a second set of pressure pulses in the drilling fluid in a second pattern, the second pattern including second encoded data,
wherein the downhole tool is configured to decode the second encoded data.
