Multiple cavity tuning of a transmitter output in a communication system

A base-site in a frequency hopping time-division multiple access (TDMA) communication system, the base-site comprising:

• a plurality of transmitters each transmitting variable frequency signals at an output during a TDMA timeslot;
• and
• a set of frequency responsive means, coupled to the output of each transmitter, for selectively frequency-tuning a transmitted signal, each frequency responsive means in the set of frequency responsive means tuned to a predetermined frequency and having an output coupled to a common antenna,
• whereby each transmitter transmits a signal at a predetermined frequency during a TDMA timeslot such that no common predetermined frequencies are transmitted via the common antenna during the same TDMA timeslot.

A base-site in a frequency hopping time-division multiple access (TDMA) communication system for transmitting a plurality of signals having different frequencies via a common antenna, the common antenna serving a plurality of subscribers in one coverage area of the communication system, the base-site comprising:

• a plurality of transmitters for transmitting the plurality of signals to the subscribers during TDMA timeslots;
• means for interconnecting the plurality of transmitters;
• a set of frequency responsive means, coupled to the output of each of the plurality of transmitters, for selectively frequency-tuning a transmitted signal, each frequency responsive means in the set of frequency responsive means tuned to a predetermined frequency and having an output coupled to a common antenna
• means, via the means for interconnecting, for instructing each of the plurality of transmitters to transmit a signal tuned to the predetermined frequency of its corresponding frequency responsive means to a subscribers during a TDMA timeslots.

A method of transmission in a frequency hopping communication system, the method comprising the steps of:

• transmitting first and second variable frequency signals via a transmitter;
• and
• selectively frequency-tuning the first and second variable frequency signals for transmission to a subscriber via a common antenna,
• whereby the transmitter frequency hops between the first and second variable frequency signals during transmissions to the subscriber via the common antenna.
