“…Comparing the summed result against a threshold value, the receiver achieves synchronization, and the information signal is detected and decoded [12]. By modifying the conventional architecture, Ching-Hung et al developed a programmablepipelined digital differential matched filter based on the Synchronization Combined PN code phase acquisition Algorithm (SCA) which utilized the 11-bit Barker code as shown in Figure 1 [8]. The SCA-based matched filter consists of pre-storage registers, multiple multipliers and adder circuits which also eventually cause high power consumption and increase the chip area.…”

“…Many algorithms and structures were proposed to reduce the power consumption and to increase the performance of the matched filters. To reduce the power consumption further, Chiou et al developed a programmable pipelined digital differential matched filter [8]. Differential coefficient schemes were first developed for low-power techniques based on the transposed-form structure [6].…”

Radio frequency identification (RFID) is the utilization of the radio frequency for the purpose of identification. RFID is lagging behind due to vendor specific solutions and excessive implementation cost. A Wireless Fidelity (WiFi) compatible IEEE 802.11 RFID tag can overcome these limitations. IEEE 802.11 utilizes Direct Sequence Spread Spectrum (DSSS) technique and a matched filter is a vital block in a DSSS system. A low-power and low-area novel adder-less Barker matched filter is proposed in this paper by eliminating the conventional multiple multiplications. The matched filter designed in 0.18 mm CMOS technology achieves average and maximum power consumption of 33.747 mW and 8.08 mW, respectively and chip area of 0.41184 mm 2 only. The simulation result shows the correct matching of data against the threshold value. Compared with the conventional matched filter, the design achieves 25% power reduction (maximum power) and 51% chip area reduction. Therefore, the design will help to implement a low-power matched filter for IEEE 801.11 compatible RFID tag.

In recent years, a new quasi‐synchronous CDMA (QS‐CDMA) system based on complete complementary codes with zero correlation zones (ZCZ), named ZCZ‐CDMA system, has been proposed. In a ZCZ‐CDMA system, data transmission efficiency can be greatly improved by accurately detecting the multi‐path properties of the communication channel utilizing the unique correlation features of the ZCZ sequence. As for the despreading operation and the code acquisition, the ZCZ‐CDMA system however is more complicated and difficult than the conventional DS‐CDMA systems. In this paper, we discuss the issues of the code acquisition in ZCZ‐CDMA systems, and propose an efficient code acquisition scheme, called two‐stage search (TSS) scheme. In the first stage of the TSS code acquisition scheme, a predictive code phase is coarsely searched, and then a fine search utilizing the unique features of the ZCZ‐sequences is carried out in the second stage. Simulation results show that the proposed scheme achieves better performance in terms of search time and hardware complexity than conventional code acquisition schemes.
