Switched antenna diversity transmission method and system

A method of transmitting information packets over a wireless communication medium to a receiver, comprising:

• encoding the information packets with an error detection code;
• modulating the error detection encoded information packets;
• transmitting the modulated information packets from a first antenna over a first forward channel of the communication medium to the receiver;
• and
• switching from the first antenna to a second antenna for transmitting the modulated packets over a second forward channel of the communication medium in response to a negative acknowledgement from the receiver transmitted over a feedback channel of the communication medium.

A transmitter for transmitting a JPEG image over a wireless communication medium to a receiver with unequal error protection, comprising:

• a separator for separating the JPEG image into Type-I and Type-II information;
• an error detection encoder for encoding the Type-I information with an error detection code;
• an error correction encoder for encoding the Type-II information with an error correction code;
• a modulator for modulating the encoded Type-I and Type-II information;
• a first antenna for transmitting the modulated Type-I and Type-II information over a first forward channel of the communication medium to the receiver;
• a second antenna for transmitting the modulated Type-I and Type-II information over a second forward channel of the communication medium to the receiver in place of the first antenna;
• and
• a switch for switching from the first antenna to the second antenna in response to a negative acknowledgment from the receiver transmitted over a feedback channel of the communication medium.
