System and method of receiving and processing multicommunication signals

A receiver operative to receive and process signals comprising two or more component carriers spaced apart in frequency, comprising:

• one or more front-end receiver circuits operative to receive and front-end process two or more component carrier signals to baseband;
• a timing estimator associated with each component carrier signal, each timing estimator operative to estimate the relative timing between a first component carrier and one or more other component carriers;
• a control unit operative to receive timing estimates from the timing estimators and control information, and operative to generate frequency and timing control signals;
• a mixer operative to receive one of the baseband component carrier signals and a frequency control signal and to generate a baseband component carrier signal frequency-aligned with the first component carrier;
• a delay unit operative to receive the frequency-aligned component carrier signal and a timing control signal, and operative to generate a baseband component carrier signal time-aligned with the first component carrier;
• and
• an adder operative to combine the first component carrier signal and one or more time-aligned and frequency-aligned component carrier signals to generate a single, combined signal;
• and
• a Fast Fourier Transform unit operative to detect symbols in the combined signal.

A controller in a receiver operative to receive and process signals comprising two or more component carriers spaced apart in frequency, the controller comprising:

• a control unit operative to receive a first timing estimate for a first received component carrier signal;
• receive a timing estimate for each of one or more other component carrier signals;
• for each other component carrier signal, calculate and output a frequency adjustment to frequency-align the component carrier signal with the first component carrier signal;
• and
• for each other component carrier signal, calculate and output a delay value to time-align the component carrier signal with the first component carrier signal.
