Comtech AHA Low Density Parity Check (LDPC) codes IP core selected for High Data Rate Demonstration
Moscow, ID – January 25, 2007 – Comtech AHA Corporation (AHA), a wholly owned subsidiary of Comtech Telecommunications Corp. (NASDAQ:CMTL), today announced that the MITRE Corporation has selected Comtech AHA’s Low Density Parity Check (LDPC) coding technology to demonstrate the effectiveness of LDPC on the High Data Rate Test Waveform. This will enable the U.S. government to further assess the use of LDPC technology across the U.S. military’s next generation satellite communications programs.
Engineers at Comtech AHA worked directly with systems engineers at the MITRE Corporation to create a new powerful LDPC coding structure that offers near optimal performance for the code rates and block size specified, while meeting the strict data rate and FPGA resource requirements of the Test Waveform.
“Comtech AHA has a long history of offering high performance forward error correction technology. This latest LDPC solution clearly surpasses the performance and FPGA resource requirements of the High Data Rate Test Waveform” said Jose Torres, Principal Signal Processing Engineer at the MITRE Corporation.
Comtech AHA Corporation’s AHA4703 LDPC IP core will fit into the Xilinx Virtex II Pro family of FPGA devices and achieves data rates above 34 Mbps for all codes. It supports 3 unique code rates with a fixed data block size of 12 k bits. The AHA4703 LDPC IP core can readily support additional FPGA families.
