Global IP Core Sales - The FH-OFDM (multicarrier) modem is developed for OFDM applications used in frequency hopping transmission scenarios or fixed frequency scenarios.

Functional Description

• Control signaling, during OFDM operation, is a 128 word (96 bits with CRC-32) that is encrypted using AES algorithm.
• Lowest SNR required for QEF performance, in case of no impairments (no SFO, no CFO and no phase noise) and code rate ½ for info block length 4K, 50 LDPC decoding iterations, and BPSK modulation is -0.25 dB.
• Supported throughputs in case of FH, BW 28 MHz, hopping rate 1K, FFT size 512, 256 QAM and LDPC code rate ⅘ with 10 decoding iterations is 114.65 Mbps.

Benefits

• Supported hopping rate: 1K hop/sec.
• Supported number of hopping channels up to 32.
• The maximum supported distance is 40 Km.
• Achievable throughput of up to 114.65 Mbps in frequency hopping mode, and up to 158.72 Mbps in fixed frequency mode of operation.

Features

• Supports LDPC code: AR4JA for rates (½, ⅔, and ⅘) and info block length (1024, 4096) bits.
• Supported OFDM sizes: 32, 64, 128, 256, 512.
• Supported modulation orders: BPSK up to 256 QAM.
• Supported oversampling ratios (4, 8).
• CRC-32 for all the FEC frames.
• Supported SFO up to 16 ppm.
• Supported CFO up to 80 KHz

Additional Features Include

• Supports LDPC code: AR4JA for rates (½, ⅔, and ⅘) and info block length (1024, 4096) bits.
