Abstract
The report describes a field survey which was made to investigate the reliability of reception of the Radio Data System (RDS). Trade-test transmissions of RDS were introduced on all BBC Band II VHF/FM radio signals broadcast in England in August 1987. A full public service of RDS is expected to commence in England in mid-1988. The survey covered both mobile (car) and static (domestic) reception under various conditions. During the survey a microcomputer was used in the survey vehicle to analyse and log the data gathered about reception of the RDS data. Particular attention was given to investigating the reception of RDS under poor receiving conditions sometimes experienced in moving vehicles.
The survey related reliability of RDS reception to quality of received sound programme. The RDS reception analysis is given in terms of 'waiting time' for correct codes (noise performance in term of bit-error-ratio statistics are not dealt with, having been studied elsewhere).
