Abstract: A mobile communication device and a data reception method implemented thereby are provided. An antenna receives a signal, and an inner receiver demodulates the received signal to generate an equalizer output. A channel decoder is coupled to the inner receiver, decoding the equalizer output to generate a data sequence. A quality estimator estimates signal quality of the received signal to generate a quality value. An error checker selectively performs cyclic redundancy code (CRC) check or CRC correction on the data sequence according to the quality value.

Abstract: A synchronization circuit includes a correlator, an energy calculator, a post-processing unit, and a decision device. The correlator correlates a received sequence r(t) with a local sequence c(i) to obtain a correlation result h(t). The energy calculator calculates an energy function of the correlation result h(t), and filters the energy function of the correlation result by a channel impulse response wc(l) to obtain a filtered energy function e(t), where l is the index of the channel impulse response. The post-processing unit applies weighting function wa(t) to the filtered energy e(t) to obtain a weighted energy function e′(t), wherein the weighting function wa(t) weights a central portion of the filtered energy function e(t). The decision device selects a maximum energy value from the weighted energy function e′(t), and the time index t with maximum energy value is the time shift of the received sequence and the local sequence.

Abstract: The present invention discloses an octave-key transfer-bar protection device, which is installed on a saxophone to protect an octave-key transfer-bar on the saxophone, and which comprises a structure body, and a collision-protection bar arranged on the structure body and encircling an accommodation space. The structure body is fixed to the external surface of the saxophone. The octave-key transfer-bar is arranged inside the accommodation space and encircled by the collision-protection bar. The collision-protection bar can protect the octave-key transfer-bar from being deformed by collision. Thus, the performer can correctly lower or raise the gamut via the octave-key transfer-bar.
