Abstract
A repeater system for wireless communication system is disclosed forthwith. The repeater system uses an analog frequency converter and digital down and up converter in order to allow the processing of the repeated signal in a relatively low frequency (in the 30 MHz range) and in a digital form (rather than in analog form). The repeater system also provides a programmable multi-band filter which can identify and suppress out of band noises to increase the signal-to-noise ratio of the system.
Claims12
A repeater system comprising:
- (a) at least one first antenna:
- (b) an analog-to-digital converter (ADC), wherein said ADC is operatively connected to said at least one first antenna;
- (c) a receive (Rx) filter, wherein said receive (Rx) filter is operatively connected to said ADC;
- (d) a first transmit (Tx) filter, wherein said first transmit (Tx) filter is operatively connected to said receive (Rx) filter;
- (e) a digital-to-analog converter (DAC), wherein said DAC is operatively connected to said first transmit (Tx) filter;
- (f) at least one second antenna, wherein said at least one second antenna is operatively connected to said first transmit (Tx) filter;
- and
- (g) a feedback channel, wherein said feedback channel is wirelessly connected to both said at least one second antenna and said at least one first (Rx) antenna.

A repeater system comprising:
- (a) a first antenna;
- (b) a first duplexer, wherein said first duplexer is operatively connected to said first antenna;
- (c) an uplink block, wherein said uplink block is operatively connected to said first duplexer;
- (d) a downlink block, wherein said downlink block is operatively connected to said first duplexer;
- (e) a second duplexer, wherein said second duplexer is operatively connected to said uplink block and to said downlink block;
- and
- (f) a second antenna, wherein said second antenna is operatively connected to said second duplexer.
