Smart dynamic selection of error correction methods for DECT based data services

A dynamic error correction system for a bi-directional digital data transmission system, comprising:

• a transmitter adapted to encode information into a signal;
• a receiver adapted to receive said signal and decode said information encoded thereon, wherein said signal is transmitted from said transmitter to said receiver via a communications channel;
• an error rate detector coupled to said receiver, said error rate detector adapted to detect an error rate in said information transmitted from said transmitter;
• a first decoder coupled to said receiver, said first decoder adapted to implement a first error correction process for said receiver;
• a second decoder coupled to said receiver, said second decoder adapted to implement a second error correction process for said receiver, wherein said second error correction process is of a higher capability than said first error correction process;
• and
• a selector coupled to receive said error rate from said receiver via a feedback channel within said communications channel and dynamically select said first decoder or said second decoder for use with said receiver in response thereto such that error correction employed by said receiver matches the condition of said communications channel, said receiver adapted to use said second error correction process to decode information on said communication channel while said transmitter uses said first error correction process to decode information on said feedback channel.

A method for a dynamic error correction system for a bi-directional digital data transmission system, the method comprising the steps of:

• a) transmitting a signal having information encoded thereon using a transmitter;
• b) decoding said signal to obtain said information using a receiver, wherein said receiver receives said signal via a communications channel;
• c) detecting an error rate in said information using an error detector coupled to said receiver;
• d) implementing a first error correction process for said receiver when said error rate is in a low state;
• e) implementing a second error correction process for said receiver when said error rate is in a higher state, wherein said second error correction process is of a higher capability than said first error correction process, the state of said error correction process detected via a feedback channel within said communications channel;
• and
• f) dynamically selecting said first error correction process or said second error correction process in response to said error rate such that error correction employed by said receiver matches the condition of said communications channel, wherein said receiver is adapted to use said second error correction process to decode information on said communication channel while said transmitter uses said first error correction process to decode information on said feedback channel.
