Abstract:
1. A wireless communication system, comprising: transmitter circuitry comprising circuitry for transmitting a plurality of frames to a receiver in a first cell; wherein each of the plurality of frames comprises a bit group; wherein the transmitter circuitry further comprises circuitry for inserting a bit sequence into the bit group; wherein the bit sequence is selected from a plurality of bit sequences such that successive transmissions by the transmitter circuitry comprise a cycle of successive ones of the plurality of bit sequences; wherein each of the plurality of frames comprises a midamble; wherein the midamble comprises the bit group; wherein the plurality of bit sequences consists of two bit sequences; wherein each of the plurality of frames has a corresponding system frame number; wherein the bit sequence is selected from the plurality of bit sequences in response to the system frame number; and wherein the bit sequence is selected from the plurality of bit sequences in response to whether the system frame number is odd or even.
