| dc.description.abstract | In communication systems, a requirement of the receiver is to estimate symbol timing so that symbol decisions may be made at the instant of smallest intersymbol interference. Though there exist various analog techniques for synchronization and detection, advances in digital signal processors (DSP) have prompted the development of algorithms that use an all-digital realization. This study focuses on an implementation of a GMSK receiver using a TMS32OC40 DSP which operates on asynchronous samples from a free running A/D converter. The GMSK receiver employs one-bit differential detection and uses Gardner's timing-error algorithm on interpolated samples for sampling phase correction. The performance of the system is tested for the cases of over-sampling and Nyquist sampling with bit-error rates comparing favorably with the analytical performance in each case. | en |
