This is a main core of finest program for POCSAG decoding.

It can be compiled by Avocet i8051 assembler/linker. 
For other assemblers some modifications of macros, 
assembler directives and/or segment definitions may be necessary.
Minimal requirement is i8752 CPU, running at 18.432 MHz.
(all usual 12 MHz CPU, which I tested, work well at this frequency)

Quartz frequency is 18.432MHz.

This program achieves very good performance due to complicated
signal processing.

Sampling frequency is 8*bit rate.

1. Filter (* 011111110 on sampling frequency) - increase SNR.
2. PLL, which maintain bit syncronisation.
3. Resulting bitstream decoded as a POCSAG codeword.
4. Correct up to 2 error in every 32-bit codeword 

This program can be distibuted freely. 

This program is provided AS IS without any warranty, expressed or
implied, including but not limited to fitness for a particular use.
Any use or not use of this software is at you own risk.
