Bluetooth transmitter, bluetooth device, and transmitter capable of improving success rate of broadcast operation

A Bluetooth device, comprising:

• a controller, configured to generate a transmission bitstream;
• and
• a Bluetooth transmitter, electrically connected to the controller, comprising:
• a digital modulation module, configured to modulate a transmission bitstream to generate a first-path modulated signal and a second-path modulated signal, wherein the transmission bitstream carries a plurality of broadcast packets;
• a first up-conversion module, electrically connected to the digital modulation module, configured to up-convert the first-path modulated signal to a first first-path up-converted signal, and up-convert the second-path modulated signal to a first second-path up-converted signal, wherein the first first-path up-converted signal and the first second-path up-converted signal are corresponding to a first broadcast channel;
• a second up-conversion module, electrically connected to the digital modulation module, configured to up-convert the first-path modulated signal to a second first-path up-converted signal, and up-convert the second-path modulated signal to a second second-path up-converted signal, wherein the second first-path up-converted signal and the second second-path up-converted signal are corresponding to a second broadcast channel;
• a first-path digital-to-analog converter, configured to generate a first-path baseband signal based on the first first-path up-converted signal and the second first-path up-converted signal;
• a second-path digital-to-analog converter, configured to generate a second-path baseband signal based on the first second-path up-converted signal and the second second-path up-converted signal;
• and
• a radio frequency circuit, electrically connected to the first-path digital-to-analog converter and the second-path digital-to-analog converter, configured to generate a broadcast signal based on the first-path baseband signal and the second-path baseband signal, wherein the broadcast signal represents the plurality of broadcast packets to be transmitted in a plurality of intervals.

A transmitter, comprising:

• a digital modulation module, configured to provide a packet to one or more up-conversion modules;
• a first up-conversion module, configured to provide to a radio frequency circuit a first up-converted signal,
• wherein the first up-converted signal carries a first replica of the packet;
• a second up-conversion module, configured to provide to the radio frequency circuit a second up-converted signal,
• wherein the second up-converted carries a second replica of the packet;
• and
• wherein the radio frequency circuit is controlled to transmit an output signal carrying the first replica and the second replica of the packet based on incorporation of the first up-converted signal and the second up-converted signal on different channels, respectively, within a single interval.
