1. A transmitter, comprising:
- a processor operative to control an initial transmission and retransmission of data; and
a memory storage device operative for storing a plurality of computer-executable instructions to be executed by the processor comprising;
a first set of instructions for receiving an initial transmission frame error rate and a retransmission frame error rate from a receiver in response to one or more previously transmitted frames;
a second set of instructions for determining and adjusting an initial transmission energy setpoint as a function of the initial transmission frame error rate and an initial transmission quality and exclusive of any retransmission frame error rate, wherein the determination of the initial transmission energy setpoint is responsive to an update trigger; and
a third set of instructions for determining and adjusting a retransmission energy setpoint as a function of the retransmission frame error rate and a retransmission quality, wherein the determination of the retransmission energy setpoint is responsive to the update trigger.
