The effect of antenna correlation and the estimation error on the dual maximal ratio combining receiver over Hoyt fading channels has been analysed in this paper. We have derived the expressions of bit error rate and outage probability to observe the quantum of performance degradation due to estimation error along with correlation. From our analysis, we have concluded that the error in envelope estimation degrades the performance of the receiver up to a great extent than the phase estimation error. Since both antenna correlation and estimation error are unavoidable in practical application, the authors feel that the provided results will assist the design engineers to sustain the quality of service in a wireless receiver.

Selection combining diversity system with antennas mounted on windshield and backlite of a vehicle is proposed for satellite digital audio radio applications. Standalone exterior mount antennas on metallic vehicles perform well for satellite digital audio radio applications, but for composite body vehicles or interior mount antennas, antenna performance becomes a real issue. Proposed on-glass two-antenna diversity is one solution for such applications. The antenna correlation is calculated using the S-parameters of the antennas and found to be very low due to many wavelengths separation between the antennas. Design of low noise amplifier, which has sub 1 dB noise figure and good P1dB due to strong cellular signals, is also detailed. A diversity receiver is described and ride tests are performed to assess the performance of the diversity system in real-time, under weak satellite signal environment which is regarded as the most challenging reception condition.
