Hi,
I'm using SIM908 in a project. The module connects well with the GPRS. But when I turn on the module and reset it cold start mode it goes back to autonomy mode. That's why it isn't picking up my location.
My command sequence is this:
GPRS_cmd("AT+CGPSPWR=1\r\n");
delay_ms(5000)...
I' working on SIM908 for a couple of days. The GPRS is working fine. At first the GPS module also worked good.
But now when I power ON the GPS module and send "AT+CGPSRST=0" to start it in coldstart mode it gives me OK response but it didn't start in that mode. And the RST is still high.
Maybe...
1. Can any body tell whats the error correction capability of the LDPC codes in case of BEC (binary erasure channel) & in case of BSC (binary symmetric channel) ?
2. How far can LDPC codes can correct burst of errors?
3. Please share some example of decoding LDPC using sum product algorithm...
