关于CC1310 FEC的问题

Other Parts Discussed in Thread: CC1310, CC2500, CC1101

TI 工程师：

这里有两个问题：

1. 关于CC1310 的FEC ，我在以下两个地方看到有不一样的回答。

2. CC1310有FEC吗？

如果有，在哪里开启的呢？与CC2500的FEC 相同吗？

如果没有，CC1310怎样与CC1101兼容通信呢?

谢谢！

1. What's the modulation scheme of HSM?

2. Does HSM adopt channel coding? If so, then what scheme is used?

4mbps on CC1310 is coded using FEC and Viterbi decoder. The effective data rate is 4.0mbps the over-the-air is higher.
1.5mbps on CC1310 is un-coded
1.0mbps on CC1310 is un-coded
5.0mbps on CC2650 is is coded using FEC and Viterbi decoder. The effective data rate is 4.0mbps the over-the-air is higher.
2.0mbps on CC2650 is un-coded
1.0mbps on CC2650 is un-coded

3. How much overhead(includig syncword and preamble) is included in the HSM?

32 bits of preamble and 32 bits of sync word is required and this is transmitted in 2FSK mode only, so therefore it effectively becomes more bits in 4 and 8FSK.

4. Regarding the receiver sensitity, I have confirmed that the sensitivity level is -84dBm in this forum.

But I couldn't see the BER which resulted in -84dBm. I want to know the specification on the receiver sensitivity of HSM.

5. Does TI support the HSM in RF studio? If so, I want to know the approximate schedule of the software release.

Not yet, but it will be included in an upcoming version. However the Patches required for TIRTOS to work at these data rates is included in the latest TI-RTOS bundle and the PER example code shows how to use it.

6. I heard that the 1.6Mbps example using 4FSK scheme is possilbe in this forum.
