Spread spectrum frequency hopping system and method

A frequency hopping spread spectrum wireless transmission method, said method comprising:

• (a) transmitting radio frequency data signals in sequential time periods on respective transmit channels according to a predetermined channel sequence, said data signal in each said time period including information relating said data signal to its position within said predetermined sequence;
• (b) monitoring a plurality of receive channels over a frequency range that includes said transmit channels;
• (c) receiving a first said data signal on a first said receive channel;
• (d) determining a next said receive channel based on said first receive channel so that said next receive channel differs from said first receive channel an amount equal to the interval between said position and the next position in said sequence;
• and
• (e) monitoring said next receive channel for a next said data signal;
• and
• (f) repeating steps (c), (d), and (e) until transmission of said data signals in said transmitting step ends, wherein said first data signal and said first receive channel of each subsequent step (c) is said next data signal and said next receive channel, respectively, of the preceding step (e).

• (b) monitoring a plurality of receive channels over a frequency range that includes said transmit channels;
• (c) detecting a first said data signal on an initial said receive channel;
• (d) monitoring for said first data signal on a higher receive channel and a lower said receive channel;
• (e) selecting one of said initial receive channel, said higher receive channel and said lower receive channel on which said first data signal is most strongly received as a first receive channel;
• (f) receiving said first data signal on said first receive channel;
• (g) determining a next said receive channel based on said first receive channel so that said next receive channel differs from said first receive channel an amount equal to the interval between said position and the next position in said sequence;
• (h) monitoring said next receive channel for a next said data signal;
• and
• (i) repeating steps (c), (d), (e), (f), (g) and (h) until transmission of said data signals in said transmitting step ends, wherein said first data signal and said initial receive channel of each subsequent step (c) is said next data signal and said next receive channel, respectively, of the preceding step (h).
