BLUETOOTH TRANSMITTER, BLUETOOTH RECEIVER, AND RECEIVER

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.
