Abstract:
1. A rate-adapting microwave communication link, comprising: a first ground based microwave terminal that is capable of transmitting a signal at one of a first data rate and a second data rate, wherein the first data rate is at least 1 gigabit/second and the second data rate that is less than 1 gigabit/second; a second ground based microwave terminal that is capable of transmitting a signal at one of a first data rate and a second data rate, wherein the first data rate is at least 1 gigabit/second and the second data rate that is less than 1 gigabit/second; wherein the first ground based microwave terminal further comprises a receive performance-level monitoring circuit that generates a signal indicating a performance level of a received signal from the second ground based microwave terminal, a logic circuit coupled to the receive performance-level estimation circuit that compares the performance level to a threshold level and a circuit that generates a signal to request a transmit rate change in the second ground based microwave terminal based on the comparison of the performance level and the threshold level; and wherein the second ground based microwave terminal further comprises a receive performance-level monitoring circuit that generates a signal indicating a performance level of a received signal from the first ground based microwave terminal, a logic circuit coupled to the receive performance-level estimation circuit that compares the performance level to a threshold level and a circuit that generates a signal to request a transmit rate change in the first ground based microwave terminal based on the comparison of the performance level and the threshold level.
