This paper shows the development of a 1024-point radix-4 FFT VHDL core for applications in hardware signal processing, targeting low-cost FPGA technologies. The developed core is targeted into a Xilinx庐 Spartan鈩?3 XC3S200 FPGA with the inclusion of a VGA display interface and an external 16-bit data acquisition system for performance evaluation purposes. Several tests were performed in order to verify FFT core functionality, besides the time performance analysis highlights the core advantages over commercially available DSPs and Pentium-based PCs. The core is compared with similar third party IP cores targeting resourceful FPGA technologies. The novelty of this work is to provide a lowcost, resource efficient core for spectrum analysis applications.

Here are the functions for Hamming code 7.4 and Extended Hamming code 8.4 encoding and decoding. For 7.4 code, one error per 7-bit codeword can be corrected. For 8.4 code, one error per 8-bit codeword can be corrected and not less than 2 errors can be detected.

A combined space鈥搕ime block coding (STBC) and eigen-space tracking (EST) scheme in multiple-input-multiple-output systems is proposed. It is proved that the STBC-EST is capable of shifting hardware complexity from the receiver to the transmitter without any bit error rate (BER) performance loss. A computation efficient EST algorithm is also proposed, which makes the STBC-EST affordable. Simulation results show that the STBC-EST with a modest feedback requirement results in a negligible BER performance loss compared with a dual system configuration.

Airline Reservations System A small airline has just purchased a computer for its new automated reservation system. You have been asked to develop the new system called ARSystem. You are to write an application to assign seats on each flight of the airline s only plane (capacity: 24 seats.) Your application should display the following alternatives: Please type 1 for FirstClass and Please type 2 for Economy. If the user types 1, your application should assign a seat in the first-class section (seats 1-8). If the user types 2, your application should assign a seat in the economy section (seats 9-24). Your application should then display a boarding pass indicating the person s seat number and whether it is in the first-class or economy
