摘要： The present invention discloses an effective apparatus and method to measure the received signal quality for a GFSK modulated signal with (or without) an unknown modulation index. The signal quality measurements are based on the decoded (unknown or known) bits and the trellis of the frequency discriminator output. This trellis is pre-calibrated with a reference Rx. The transmitted modulation index is also accurately estimated in this invention.

摘要： The present invention discloses a method and apparatus to provide, effectively and robustly, a phase reference in phase-domain for digital phase-modulated signals. Not only the first-order but also higher order PLLs are delineated for robust and fast tracking of frequency errors and time-varying frequency errors between the transmitter and the receiver. This invention can be applied to any phase-modulated signal such as PSK, DPSK, π/4-DPSK, and CPM. The decoders with this invention can achieve close to the performance of coherent detection.Reference[1] D. Divsalar and M. K. Simon, “Multiple-symbols differential detection of MPSK,” IEEE Trans.

摘要： An acquisition scheme for receiving a Bluetooth basic data rate (BDR) or enhanced data rate (EDR) packet. A simplified acquisition apparatus for a Bluetooth receiver having a phase differentiator, a plurality of basic building blocks, a plurality of 1-bit switch, and a correlation computation equation. It features a simplified acquisition circuit implementation with a 1-bit correlator hardware shared by access code and EDR synchronization sequence correlation computations. A 4 MHz sampling rate is used for correlation computation. A SINC interpolator is then used to get an 8 or 16 MHz timing resolution for data bit decoding. Based on the measurement results, this simple acquisition scheme can support successful decoding of a received Bluetooth packet with a maximum timing offset of +/−40 ppm and a maximum frequency offset of +/−60 ppm without loss of receiver sensitivity.
