the pseudo random code generator 216 and clock generator 214 in the manner as discussed above if this particular pager receiver 200 is the mth user being 34 paged 34 i e addressed the pn coded signal 230 represents the same sequence a m of l numbers as used by the paging signal source 18 i e z m y m this will be true because the address memory 250 provides a start address 252 to the receiver 39 s pseudo random code generator 216 which corresponds to the start address 132 used in the pseudo random code generator 112 in the pager signal source 18 as discussed above this produces a demodulated signal 232 representing the original k bit message word x m this demodulated signal 232 representing the original k bit message word x m is decoded by a format decoder 210 to produce a signal 234 representing the original k message bits this format decoded signal 234 is then further decoded by an output decoder to selectively produce output signals 238 242 246 representing the k message bits for display on some form of display device 240 e g liquid crystal display for playback on an audio device 244 e g speaker or storage in some form of memory device 248 e g random access memory further information regarding the above discussed encoding and decoding technique can be found in the following references j k holmes amp c c chen 34 acquisition time performance of pn spread spectrum systems 34 ieee transactions on communications vol com 25 no 8 august 1977 pp 778 83 e l key 34 an analysis of the structure and complexity.
