    Abstract: A variable rate transmission system where a packet of variable is transmitted on a traffic channel if the capacity of the traffic channel is greater than or equal to the data rate of the packet. When the rate of the packet of variable rate data exceeds the capacity of the traffic channel, the packet is transmitted on a traffic channel and at least one overflow channel. Also described is a receiving system for receiving and reassembling the data transmitted on the traffic channel and at least one additional overflow channels.

    Abstract: The present invention discloses a variable rate transmission system wherein a packet of variable rate data is modulated in accordance with a traffic channel sequence supplied by a traffic PN generator (63) if the capacity of said traffic channel is greater than or equal to said data rate of the packet. If the capacity of said traffic channel is less than said data rate, the packet of variable rate data is modulated in accordance with the traffic channel sequence supplied by the traffic PN generator (63) and in accordance with at least one overflow channel sequence supplied by an overflow channel generator (65). The present invention further discloses a receiving system for receiving variable rate data where a received packet of variable rate data is demodulated in accordance with a traffic channel sequence supplied by a traffic PN generator (104) if the capacity of said traffic channel is greater than or equal to a data rate of said packet. If the capacity of said traffic channel is less than said data rate of the packet of variable rate data, the received packet is demodulated in accordance with a traffic channel sequence supplied by a traffic PN generator (104) and in accordance with at least one overflow channel sequence supplied by an overflow channel generator (120).
