I am looking for some reference regarding the coding gain when FEC is enabled.
1. Is it 802.15.4g FSK mode FEC? (CC rate ½ K=4), Can it also use OQPSK FEC mode? (CC rate ½ K=7)
2. Is ADF7030-1 receive based on Viterbi decoding? If so, what is the window length, hence the latency for FEC-encoded Rx?
3. Since ADF7030-1 supports GMSK and 4FSK, I assume the RF should be bale to support BPSK. Isn’t that achievable by updating the Cortex M0 firmware?
4. ADuCM03x 256kB Flash / 64kB RAM is a good fit for our application, despite its relatively slow 26MHz clock. Could it support 2x SPI interfaces + 2 UART? If so, do you have a FreeRTOS port with tickles sleep mode readily available, or some reference code?
Hi Kenton Chu,
1. The FEC in IEEE 802.15.4g packet mode has a constraint length of K=4, and a code rate of 1/2. FEC is not available using OQPSK.
2. No information has been provided on the receiver decoding…
2. No information has been provided on the receiver decoding algorithm. There's also no available data on latency. The ADF7030-1, however, conforms with the IEEE 802.15.4g standard. For more information, please refer to the IEEE 802.15.4g-2012 standard. You may also contact your local FAE.
3. The firmware does not support BPSK.
4. Support for ADuCM30x has a different forum. Please raise your question to the forum provided by the link below
