Abstract
A digital radio communication is transmitted by generating a digital message to be transmitted and generating an error detection code corresponding to the digital message. The error detection code is logically combined with a predetermined number thereby generating a transmission code, and the digital message and the transmission error code are transmitted over a radio channel. More particularly, the predetermined number and the error detection code can be logically combined using the exclusive-OR function.
Claims40
A method of transmitting a digital radio communication, said method comprising the steps of:
- generating a digital message to be transmitted;
- generating an error detection code corresponding to the digital message;
- after said step of generating the error detection code, logically combining the error detection code with a predetermined number thereby generating a transmission code;
- and
- transmitting the digital message and the transmission code over a radio channel.
A method of receiving a digital radio communication over a radio channel wherein the digital radio communication includes a digital message and a transmission code and wherein the transmission code is generated by logically combining an error detection code with a predetermined number prior to transmission over the radio channel, the method comprising the steps of:
- receiving the digital message and the transmission code over the radio channel;
- logically combining the transmission code with the predetermined number thereby recovering the error detection code;
- and
- after logically combining the transmission code with the predetermined number, performing error detection on the received digital message using the recovered error detection code.
A transmitter for transmitting digital radio communications including a digital message, the transmitter comprising:
- means for generating an error detection code corresponding to the digital message;
- means for logically combining the error detection code with a predetermined number after generating the error detection code thereby generating a transmission code;
- and
- means for transmitting the digital message and the transmission code over a radio channel.
A receiver for receiving digital radio communications over a radio channel wherein the digital radio communication includes a digital message and a transmission code and wherein the transmission code is generated by logically combining an error detection code with a predetermined number prior to transmission over the radio channel, the receiver comprising:
- means for receiving the digital message and the transmission code over the radio channel;
- means for logically combining the transmission code with the predetermined number thereby recovering the error detection code;
- and
- means for performing error detection on the received digital message using the recovered error detection code.
