摘要： Methods and systems that enhance interference cancellation in communication channels are described. Specialized time domain training sequences and simple cross correlation are used to obtain a channel estimate for use in stacked carrier beamforming and OFDM based spatial beamforming. In certain embodiments, a time domain preamble sequence is provided as an alternative to the conventional frequency domain preamble sequence. The use of a time domain preamble can increase channel estimation performance, facilitating cancellation of co-channel interference. Embodiments include generating a training sequence preamble in the time domain, computing a frequency domain response of the channel using an estimate of its time domain impulse response, and using the frequency domain response of the channel to calculate channel estimation from a cross correlation of data received from the channel against the training sequence.

摘要： A method and system of collecting local television signals includes a local collection facility a plurality of primary receiver circuit modules comprising a first receiver circuit module. The first receiver circuit module receives and demodulates the first channel signal and forms an IP signal. A remote facility is spaced apart from the local collection facility and communicates with the local collection facility through an IP backhaul. A primary decoder within the remote facility is in communication with the IP backhaul and forms a decoded signal from the IP signal. A primary encoder within the remote facility in communication with the primary decoder forms a first encoded signal from the decoded signal. A multiplexer in the remote facility multiplexes the first encoded signal into a multiplexed signal. The multiplexed signal may provide an output signal used for uplinking or other type of distribution.

摘要： A receiver and method for operating the same includes a memory storing purchase information therein and a communication module. A controller is in communication with the memory and the communication module. The controller determines whether an existing Internet connection is present at the communication module when the existing Internet connection is present and communicates purchase information to a service provider through the existing Internet connection. The controller determines whether a subscriber-initiated Internet connection has occurred within a mandatory callback time period, when purchase information has been communicated within the mandatory callback time period and advances the mandatory callback time period. The controller initiates the communication module to initiate a new Internet connection when there is no existing Internet connection present or no subscriber-initiated Internet connection has occurred within the mandatory callback time period.
