The performance of a digital matched filter receiver with multi-bit quantized correlators for Direct Sequence Spread Spectrum (DSSS) mobile satellite applications is evaluated with experiments. A Coherent Matched Filter (CMF) technique is used to accomplish fast code acquisition, automatic frequency control and coherent detection of data with a single matched filter circuit to satisfy the requirements for the mobile satellite applications. Loop-back test and field test results in suburban areas with the ETS-V satellite are presented, in which the use of multi-bit quantized correlators improve the initial acquisition and the bit error rate performances. The dynamic performance of the CMF receiver is confirmed to be satisfactory for the mobile satellite fading channels.
