Partial radio block detection

1. A method comprising:

receiving an interleaved radio block from a communication channel, the radio block comprising a plurality of sub-blocks wherein each sub-block has first data and second data;

evaluating the first data of the interleaved radio sub-block to obtain a first evaluation result, wherein the act of evaluating the first data comprises determining a first sum of the first data;

evaluating the second data of the interleaved radio sub-block to obtain a second evaluation result, wherein the act of evaluating the second data comprises determining a second sum of the second data and wherein the first data is evaluated independent of the second data; and

determining whether the interleaved radio block is a partial block based on the independent evaluations of the first and second data wherein the partial block includes half valid data, wherein the act of determining whether the radio block is a partial block comprises determining an average of the first and second sums and comparing the first and second sums to the average.

2. The method of claim 1 , wherein the first data is associated with a first speech frame and the second data is associated with another speech frame.

3. The method of claim 2 , wherein the first data comprises a portion of the first speech frame after the application of speech and channel encoding.

4. The method of claim 1 , wherein the act of comparing the first and second sums to the average further comprises: comparing the first and second sums to a scaled average.

5. The method of claim 1 , further comprising: selectively setting a flag to indicate whether the radio block is a partial block.

6. The method of claim 1 , wherein the first and second data are interleaved at the bit level in the radio block.

7. The method of claim 1 , wherein the first data comprises even bits from a first encoded block and the second data comprises odd bits from a second encoded block.

8. An apparatus comprising:

a buffer to receive an interleaved radio block of incoming wireless data, the radio block comprising a plurality of sub-blocks wherein each sub-block has first data and second data; and

a channel decoder to determine whether the interleaved radio block is valid based on results obtained by independent evaluations of the first and second data of the interleaved radio sub-block wherein an invalid radio block includes half valid data; and wherein the channel decoder independent evaluations comprise the channel decoder being adapted to determine a first sum of the first data; being adapted to determine a second sum of the second data; compare the first and second sums to a combination of the first and second sums and base the determination of whether the radio block is valid on the comparison.

9. The apparatus of claim 8 , wherein the first data is associated with a first speech frame and the second data is associated with another speech frame.

10. The apparatus of claim 8 , wherein the first and second data are interleaved at the bit level in the radio block.

11. The apparatus of claim 8 , wherein the first data comprises even bits from a first encoded block and the second data comprises odd bits from a second encoded block.

12. A mobile station comprising:

a radio to receive an interleaved radio block of wireless data from a wireless communication channel, the radio block comprising a plurality of sub-blocks wherein each sub-block has first data associated with a first speech frame and second data associated with a second speech frame;

a digital signal adapted processor to determine whether the interleaved radio block is a partial block based on results obtained from independent evaluations of the first and second data wherein the partial block includes data from only one speech frame; and the independent evaluations comprising the digital signal processor being adapted to determine whether the radio block is a partial block based on the sum of the first data and a sum of the second data and a comparison of the sum of the first data and the sum of the second data with an average of the first and second sums of data.

13. The mobile station of claim 12 , wherein the digital signal processor is adapted to selectively set a flag to indicate when the radio block is a partial block.

14. An article comprising a storage medium accessible by a processor-based system and storing instructions that when executed cause the processor-based system to perform:

receiving an interleaved radio block via a communication channel, the radio block comprising a plurality of sub-blocks wherein each sub-block has first data and second data; and

determining whether the interleaved radio block is a partial block based on results obtained from independent evaluations of the first and second data of the interleaved radio sub-block wherein the partial block includes half valid data; determining a first sum of the first data; determining a second sum of the second data; determining whether the radio block is a partial block based on a combination of: determining an average of the first and second sums; and comparing the first and second sums to the average.
