Digital audio transmitter and receiver

1. A method of transmitting and receiving a signal comprising digitally encoded packets, comprising the steps of:

a. Interleaving elements of a predetermined number of packets of a signal;

b. Determining if the signal should be folded;

c. Detecting missing or damaged elements;

d. Estimating the values of the missing or damaged elements by interpolation using a polynomial curve fit; and

e. Unfolding the signal.

2. The method of claim 1 further comprising the step of folding the signal.

3. The method of claim 1 wherein the missing or damaged elements are detected using a checksum process.

4. The method of claim 1 wherein the missing or damaged elements are detected using a cyclic redundancy check.

5. A method of transmitting and receiving a signal comprising digitally encoded packets, comprising the steps of:

a. Interleaving the elements of a predetermined number of packets of a signal;

b. Folding the signal;

c. Applying a process to detect missing or damages elements of the signal after it has been transmitted;

d. Applying a polynomial curve to interpolate the values of the missing or damaged elements of the signal; and

e. Unfolding the signal.

6. A method of preserving the power of a signal in transmission, comprising the steps of:

a. interleaving the elements of an original signal to be transmitted at a 48 kHz audio rate with radio link at 18 Mbps,

b. transmitting the signal,

c. interpolating values for missing or damaged elements detected in a checksum process or cyclic redundancy process, and

d. unfolding the signal; where the unfolded signal has a SINAD greater than 60 dB and a received power level of −80 dBm to −71 dBm.
