Wireless-wireline physically converged architectures

A wireline-to-wireless access node comprising:

• a wireline interface that receives a frequency-scaled time-duplexed signal;
• an analog-to-digital converter coupled to the wireline interface, the analog-to-digital converter converts the frequency-scaled time-duplexed signal to a frequency-scaled digital signal;
• a frequency-descaling buffer coupled to receive the frequency-scaled digital signal, the frequency-descaling buffer stores a plurality of symbols within the frequency-scaled digital signal and subsequently outputs descaled samples at a first rate;
• a digital-to-analog converter coupled to receive the outputted descaled samples, the digital-to-analog converter converts the descaled samples to a descaled analog signal;
• and
• a wireless interface coupled to receive the descaled analog signal, the wireless interface modulates the descaled analog signal to a selected channel carrier frequency and transmits the modulated analog signal on a wireless link.

A method for communicating a wireless and wireline signal, the method comprising:

• receiving a wireless signal;
• demodulating the first signal to an analytic signal by sampling the first signal at a first sampling rate;
• generating an interpolated signal by interpolating the analytic signal at a second rate, the second rate being faster than the first rate;
• scaling the frequency of the interpolated signal across a plurality of time slots to generate a frequency-scaled time-duplexed signal;
• converting the frequency-scaled time-duplexed signal into an analog frequency-scaled time-duplexed signal;
• transmitting the analog frequency-scaled time-duplexed signal onto a wireline link;
• receiving the analog frequency-scaled time-duplexed signal from the wireline link;
• converting the analog frequency-scaled time-duplexed signal to a frequency-scaled digital signal;
• generating a plurality of descaled symbols from the frequency-scaled digital signal;
• converting the plurality of descaled symbols to an analog signal;
• and
• transmitting the analog signal on a wireless link by modulating the analog signal on a selected carrier signal.
