Abstract: A Bluetooth transmitter, a Bluetooth receiver, and a receiver are provided. The Bluetooth transmitter includes modulation modules, up-conversion modules, and an RF transmitting circuit. The modulation modules modulate transmission bitstreams to generate multiple pairs of modulated signals. The up-conversion modules up-convert the pairs of modulated signals to multiple pairs of up-converted signals. The RF transmitting circuit transmits an output signal based on the pairs of up-converted signals. The Bluetooth receiver includes an RF receiving circuit, down-conversion modules, and de-modulators. The RF receiving circuit transforms an input signal into a pair of analog filtered signals. The down-conversion modules generate pairs of down-converted signals based on the pair of analog filtered signals. The de-modulators generate received bitstreams by demodulating the pairs of down-converted signals.

Abstract: A Bluetooth transmitter, a Bluetooth device, and a transmitter are provided. After being received by the transmitter, a transmission bitstream is modulated to generate a first-path modulated signal and a second-path modulated signal, which are up-converted to a first first-path up-converted signal, a second first-path up-converted signal, a first second-path up-converted signal, and a second second-path up-converted signal. The first first-path and the second first-path up-converted signals are corresponding to a first broadcast channel, and the first second-path and the second second-path up-converted signals correspond to a second broadcast channel. A first-path baseband signal is generated based on the first first-path and the second first-path up-converted signals, and a second-path baseband signal is generated based on the first second-path and the second second-path up-converted signals. A broadcast signal is generated based on the first-path and the second-path baseband signals.
