摘要： A method apparatus are provided for mitigating spectral lines in a wireless signal. First a code word is generated that is made up of a plurality of binary or ternary encoded pulses. Then a plurality of code-word-modulated wavelets are generated in response to the code word. These wavelets can be Gaussian monopulses, repeated cycles of a sine wave, or other shaped impulse signals. The plurality of code-word-modulated wavelets are then modulated with a bit of transmit data to form a plurality of data-modulated wavelets. This modulation serves to whiten the signals since the transmit data is effectively random. Finally, the plurality of data-modulated wavelets are transmitted to a remote device.

摘要： In the present invention, an ADSL system (10) identifies good bin as a bin capable of successfully transmitting data to a destination. A bad bin is identified as a carrier that is not capable of successfully transmitting data to the destination. A marginal bin is identified as a carrier that may be capable of transmitting data to the destination. The power to a bad bin is reduced and allocated to the marginal or good bin(s) to allow an increased bit rate. In another embodiment, the power to marginal bin is reduced and allocated to the good bin(s).
