A signal characteristic of the receiver baseband signal is measured in the presence of phase shifts introduced in the transmitter output signal. Joint LO IQ imbalance figures of merit are computed from the signal characteristic measurements, each characterizing signal processing artifacts in the receiver baseband signal caused by joint signal processing in the transmitter and the receiver under influence of transmitter LO IQ imbalance and receiver LO IQ imbalance. The LO IQ imbalance correction data are determined from the computed JFMs so that the transmitter LO IQ imbalance is distinctly characterized from the receiver LO IQ imbalance from measurements obtained through no greater than two (2) phase shifts. | 2014-10-30 |
20140321517 | NETWORK TERMINATION EQUIPMENT - The present invention provides an improved network termination equipment (NTE). The NTE of the present invention comprises a VDSL modem such that telephony signals and data signals can be transmitted together over conventional telephone wiring, without the need to install data cabling. This makes installation of super-fast broad band services faster and cheaper and makes them less visually intrusive. | 2014-10-30 |
