Filtering method to allow FDD and TDD operation in PCS transreceivers |
摘要 |
A transreceiver allows efficient operation in a full or half-duplex TDD or FDD system. The preferred transreceiver includes a common set of filters used for both FDD (Frequency Division Duplex) and TDD (Time Division Duplex) operation in a given range of frequencies thereby reducing circuitry count and implementation costs. Thus, the transreceiver of the present invention can operate in FDD operation or TDD operation.
