In this paper, an Ultra High Frequency (UHF) base band processor for a passive tag is presented. It proposes a Radio Frequency Identification (RFID) tag digital base band architecture which is compatible with the EPC C C2/ISO18000-6B protocol. Several design approaches such as clock gating technique, clock strobe design and clock management are used. In order to reduce the area Decimal Matrix C...

The base-band analog processor performs necessary signal processing on the 150 MHz base-band signal in the transmit and receive signal paths for a wide-band wireless local area network. The individual channel characteristics depend on the RF signal fade and interference. Broadcasting to multiple appliances requires channel equalization at the receiver. In the receive (Rx) section, the wide-band...

A low power implementation of a secure EPC UHF passive digital base band processor will be designed for UWB transceiver on RFID for wireless application. To ensure the secure information transaction of the passive tag, traditionally the focus is on directly applying a low complexity encryption engine. The attackers could make use of known header to reveal the secret key. The proposed architectu...

In this paper, we describe the software implementation of a GSM base station and consider the performance of each of its Radio Interface components. The performance of each software module is evaluated using both a % CPU metric and a processor-independent metric based on SPEC benchmarks. These results can be used to dimension systems, e.g., to estimate the number of GSM channels that can be sup...

This paper describes the SpectrumWare testbed and two experimental systems we are developing: an ATM-based wide-band receiver and the receive side of a GSM base station. These projects leverage recent advances in processor and analog-to-digital conversion technology that have enabled a software-oriented approach to wireless communication and distributed sample processing.

The objective of this design is to made a design of 128/64 point Fast Fourier transform processor to support future generation MultipleInput Multiple Output Orthogonal Frequency Division Multiplexing (MIMO -OFDM). 1n wireless local area network base band processor the architecture produces high complexity. The pipelined mixed radix multipath delay feedback (MRMDF) FFT architecture is proposed t...
