Novel Access Methods in Cellular Networks based on the Analog Bloom Filter

In cellular networks, the User Equipment (UE) often needs to send control information base station. For example, initiate a connection, UE transmits Zadoff-Chu (ZC) sequence on channel called PRACH, where is randomly selected from up 64 sequences. Also, connected may Scheduling Request (SR) bit PUCCH start an uplink data transmission. this paper, novel access methods, namely, ABF PRACH and SR, are proposed based Analog Bloom Filter (ABF). With pattern, which consists of multiple ZC The performance improved, because number patterns, currently 2304, much larger than sequences, resulting in lower collision probability. Similarly, with each assigned unique pattern. system capacity resource shared by many UEs, instead dedicated individual UEs. Both SR have been demonstrated real-world experiments. Simulations show that significantly outperforms existing PRACH. ABR achieves 2.52-fold increase capacity, while maintaining very low error ratios.
