Patent ID: 8412116

Claim:
A method for transmitting and receiving signals in a communication system comprising: receiving a received signal, wherein the received signal is split into an in phase (I) component and a quadrature (Q) component; configuring a local oscillator to generate a receiver local oscillator signal, the local oscillator including a phase locked loop (PLL) having a divide ratio controlled by a divider and a voltage controlled oscillator having an output that changes in response to changes in the divide ratio, said configuring further comprising controlling the divider to generate a receive divide ratio in response to channel information pertaining to the received signal; demodulating the I and Q components of the received signal by mixing each of the components of the received signal with the receiver local oscillator signal; sampling the demodulated I and Q components simultaneously; delaying one of the Q component and the I component from the other by a time delay and interleaving, according to the time delay, the sampled demodulated I and Q components into a received data sequence; switching the configuration of the local oscillator to generate a transmission signal for use by a transmitter, wherein switching comprises switching at least one port of the local oscillator from a receive path to a directly modulated transmit path including switching an input port of the divider from a receive path including the channel information pertaining to the received signal to a transmit path including a digitized transmit input signal; generating a directly modulated transmission signal at the output of the voltage controlled oscillator by changing the divide ratio of the PLL in response to the digitized transmit input signal; and transmitting the directly modulated transmission signal.
