1. A Bluetooth signal receiving device comprising: a frequency shift demodulator circuit configured to generate a baseband signal by performing frequency shift modulation on a received signal; a sampler circuit configured to: sample the baseband signal based on a symbol timing; and generate a plurality of series of bit streams based on sampled values; a training bit pattern discriminator circuit configured to determine whether the plurality of series of bit streams generated by the sampler circuit satisfies a training bit pattern condition; and a symbol timing offset compensation circuit configured to compensate the symbol timing of the baseband signal based on a measured error metric as an effective error metric if the plurality of series of bit streams satisfies the training bit pattern condition.
