Abstract: Disclosed are various embodiments providing carrier separation to effectuate a dual carrier operation of a wireless communication device. Processing circuitry may acquire a single carrier signal based on a determined time slot boundary, the single carrier signal comprising primary carrier data. The processing circuitry may receive a dual carrier radio frequency signal based on the determined time slot boundary, the dual carrier radio frequency signal comprising the primary carrier data and secondary carrier data. The processing circuitry may then generate a baseband dual carrier signal by demodulating the dual carrier radio frequency signal. The processing circuitry may separate the primary carrier data from the baseband dual carrier signal by filtering the baseband dual carrier signal. The processing circuitry may also separate the secondary carrier data from the baseband dual carrier signal by filtering the baseband dual carrier signal.
