Abstract: Systems, methods, and devices for reducing interference with digital television transmissions occurring over a bandwidth are disclosed. The digital television signal is correlated to a reference digital television field sync signal. A non-coherent correlation power measurement is determined based on the correlation of the received digital television signal to the reference digital television field sync signal. A plurality of maximum non-coherent correlation power measurements are determined over multiple field times. An energy estimate for the digital television transmission is determined based on the maximum non-coherent correlation power measurements. A transmit mask filter is generated based on the energy estimate. The transmit mask is applied to transmissions to reduce interference with detected digital television transmissions.

Abstract: In general, the subject matter described in this specification can be embodied in methods, systems, and program products for adapting data rate in a communication system. A receiving device receives a data transmission at an initial data rate. The device determines, based on an error rate of the data transmission at the initial data rate, that a first criterion is satisfied for requesting an increase in the data transmission. The device requests that a transmitting device increase the data transmission from the initial data rate to the first subsequent data rate. The device determines, based on an error rate of the data transmission at the first subsequent data rate, whether a second criterion is satisfied for maintaining the first subsequent data rate. The device maintains, if the second criterion is determined to be satisfied, a state of the device for receiving the data transmission at the first subsequent data rate.
