Radio Transceiver Pipeline
1 TRANSITION DELAY MODEL computes the time required for a transmission to complete
2 LINK CLOSURE MODEL determines which receivers can be reached by the transmission (the rest of the Pipeline will be executed separately for each receiver that passes this test)
3 CHANNEL MATCH MODEL determines which receiver channels can demodulate the transmission, and which ones should treat it as noise
4 TRANSMITTER ANTENNA GAIN MODEL computes the gain of the transmitter's antenna in the direction of the receiver
5 PROPOGATION DELAY MODEL computes the time required for the transmitted signal to propagate between the transmitter and the receiver
6 RECEIVER ANTENNA GAIN MODEL computes the gain of the receiver's antenna in the direction of the transmitter
7 RECEIVED POWER MODEL computes the average received power of a transmission (typically factoring in antenna gains, channel frequency, transmitter power, distance, etc.). Fading effects can be incorporated here.
8 BACKGROUND NOISE MODEL computes the in-band background noise for a receiver channel
9 INTERFERENCE NOISE MODEL computes the interference noise which affects a transmission fragment (typically, the total power of all other concurrent, in-band transmissions)
10 SNR MODEL computes the SNR of a transmission fragment (usually based on the ratio of received power to the sum of background and interference noise)
11 BER MODEL computes the mean bit error rate (BER) over each constant SNR fragment of the transmission
12 ERROR ALLOCATION MODEL determines the number of bit errors in each fragment of the transmission
13 ERROR CORRECTION MODEL determines whether the allocated transmission errors can be corrected and if the transmitted data should be forwarded into the node for higher level processing
